A “bottom-up” approach to process development: Application of physicochemical properties of reaction products toward the development of direct-drop processes

The “bottom-up” approach to development of direct-drop processes is a powerful, yet simple, strategy that every process chemist should consider for the development of efficient, cost-effective, and environmentally friendly processes. This approach is aided by a “parallel crystallization” technique, which allows for rapid identification of multiple solvent systems for the crystallization of the desired product using a minimal amount of material and solvent. This “bottom-up” approach is illustrated by several examples where the desired product is crystallized directly from the reaction mixture.

Design and synthesis of aminothiazole based Hepatitis B Virus (HBV) capsid inhibitors

The capsid assembly is an essential step for Hepatitis B Virus (HBV) life cycle and is an important target for anti-HBV drug development. In this report, we identified a hit compound with aminothiazole structure by the high throughput screening (HTS) which inhibited the interaction of HBV capsid protein within the cells. The structure hopping and SAR studies of the hit compound afforded compound 79 with potent anti-HBV replication activity and good basic drug-like properties. The working mechanism studies showed that compound 79 could bind to the similar binding site of known HBV capsid inhibitor with heteroaryldihydropyrimidine (HAP) scaffold, through similar hydrophobic interactions but with a different hydrogen bond. This compound exerted potent inhibitory effect upon HBV production, either in cell culture or in mice with no obvious acute toxicity. We propose that further development of this compound could lead to novel potent anti-HBV inhibitors that target HBV capsid assembly.

Synthesis, structure and pyrolysis of stabilised phosphonium ylides containing saturated oxygen heterocycles

A range of twelve stabilised phosphonium ylides containing tetrahydrofuran, tetrahydropyran or 2,2-dimethyl-1,3-dioxolane rings have been prepared and fully characterised, including one X-ray structure determination of each type. The X-ray structures confirm the P=C and C=O functions to be syn and all the compounds undergo thermal extrusion of Ph3PO to give the corresponding alkynes. In some cases there is also competing loss of Ph3P to give different carbene-derived products and evidence has been obtained for the generation of 2-phenyloxete in this way. Raising the pyrolysis temperature leads in several cases to new secondary reactions of the alkyne products involving a sequence of alkyne to vinylidene isomerisation, intramolecular CH insertion, and retro Diels Alder reaction.

Design and Biological Evaluation of Furan/Pyrrole/Thiophene-2-carboxamide Derivatives as Efficient DNA GyraseB Inhibitors of Staphylococcus aureus

DNA topoisomerases are well-validated targets in micro-organisms. DNA gyraseB is one of the most important enzymes among them as per their clinical importance.

Safe, selective, and high-yielding synthesis of acryloyl chloride in a continuous-flow system

Acid chlorides are an important class of compounds and their high reactivity and instability has prompted us to develop a straightforward procedure for their synthesis with ondemand and on-site synthesis possibilities. The focus of this report is acryloyl chloride, mainly important for the acrylate and polymer industry. A continuous-flow methodology was developed for the fast and selective synthesis of the otherwise highly unstable acryloyl chloride. Three routes were investigated in a microreactor setup and all three can potentially be used for its production. The methodology was further expanded to the synthesis of other unstable acid chlorides by both the thionyl chloride and the oxalyl chloride mediated processes. The most sustainable method was the oxalyl chloride mediated procedure under solvent-free conditions, in which nearequimolar amounts of carboxylic acid and oxalyl chloride were used in the presence of catalytic amounts of DMF at room temperature. Within 1 to 3 min, nearly full conversions into the acid chlorides were achieved.

Staudinger reactions of unsymmetrical cyclic ketenes: A synthetically useful approach to spiro beta-lactams and derivatives. Reaction mechanism and theoretical studies

An efficient and operationally simple synthesis of tetrahydrofuran-derived spiro-beta-lactams using the ketene-imine cycloaddition route is described. Also the preparation of spiro-N-sulfonyl-beta-lactam derivatives, which are analogs of monobactams, is reported. As far as we know, this is the first time that an unsymmetrical cyclic ketene is used in a Staudinger-type reaction. The experimental evidence suggests the involvement of a ketene derived from the acyl chloride precursor in the reaction. High-level ab initio calculations have been performed in order to get insight into the electronic effects controlling the stereochemical outcome of the reactions.

New insights into the torquoselectivity of the staudinger reaction

To understand the torquoselectivity and the electronic effects of the Staudinger reaction, a study using a combination of experiments and DFT calculations has been conducted for the reactions of an unsymmetric cyclicketene and cyclic imines with different electronic properties. The pred ominant formation of the donor-in beta-lactams, the torquoelectronically disfavored products, was observed for the first time. The Hammett analyses reveal a close relationship between the donor-out/donor-in productratio and the electronic nature of the imines. The kinetic competition experiments and DFT calculations indicate that the two-step Staudinger r eaction shows different rate-determining steps in the donor-in and donor-out pathways. Our investigations reveal that the torquoelectronic control in the Staudinger reaction is quite different from that in the ring-opening reaction of cyclobutene derivatives. The diastereoselectivity of the Staudinger reaction involving an unsymmetric disubstituted ketene cannot be simply rationalized or predicted by the torquoelectronic model.
