Photoredox-catalyzed decarboxylative alkylation/cyclization of alkynylphosphine oxides: a metal- and oxidant-free method for accessing benzo[b]phosphole oxides

By photoredox-catalysis, alkylation/aryl C-H cyclization of readily available alkynylphosphine oxides towards benzo[b]phospholes has been realized under metal- and oxidant-free conditions at room temperature. This reaction readily incorporates various functionalized alkyl groups into the benzo[b]phosphole skeletons, representing a mild and versatile tool for the preparation of valuable phosphole compounds.

Enantioselective haloetherification by asymmetric opening of meso -halonium ions

A new approach to enantioselective haloetherification reactions via desymmetrization of in situ-generated meso-halonium ions is described. The combination of N-haloamides as a halogen source and sodium salts of chiral phosphoric acids as catalysts can be used for the cyclization of symmetrical ene-diol substrates, yielding the haloetherification products under practical conditions in enantioenriched form.(Figure Presented)

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Application In Synthesis of (S)-(Tetrahydrofuran-2-yl)methanol, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 57203-01-7, in my other articles.

Samarium(II)-mediated 4-exo trig ketyl-olefin cyclisation of unsaturated aldehydes. A general, stereoselective synthesis of functionalised cyclobutanols

gamma,delta-Unsaturated aldehydes having a quaternary centre in either the alpha or beta-position, have been prepared from substituted gamma-butyrolactones and undergo efficient 4-exo-trig ketyl-olefin cyclisation on treatment with samarium(II) iodide to give functionalised cyclobutanols. In all cases cyclisation occurs with complete diastereocontrol to give anti-cyclobutanol products. In the cyclisation of substrate 4ab, significant stereochemical control is achieved at three contiguous chiral centres. Both unsaturated esters and vinyl sulfones have been employed as substrates in the reaction.

Synthetic approaches to the daphnane and tigliane diterpenes from aromatic precursors

Synthetic studies toward the daphnane and tigliane diterpenes, a large family of natural products from the plant families Euphorbiaceae and Thymelaeaceae, are reported. Retrosynthetic analysis traced these molecules back to an aromatic precursor and several routes were explored in the forward direction to access such motifs. Two strategies ultimately proved capable of forging complex 5,7,6-fused tricyclic ring systems, one of which proceeded in only seven steps.

Characterization of important sulfur and nitrogen compounds in Lang baijiu by application of gas chromatography-olfactometry, flame photometric detection, nitrogen phosphorus detector and odor activity value

The volatile compounds in three Lang baijiu (?Honghualangshi, Y1?, ?Langjiulangge, Y2?, and ?Laolangjiu, Y3?) were identified by gas chromatography-olfactometry (GC-O), gas chromatography-mass spectrometry (GC?MS), flame photometric detection (FPD), and nitrogen phosphorus detector (NPD) with the aid of stir bar sorptive extraction (SBSE). The results showed that a total of 60, 62, and 61 compounds with aroma contribution were present in samples Y1, Y2, and Y3, respectively. Additionally, the odor activity value (OAV) was used to evaluate the important compounds. The results indicated that 2-methyl-3-furanthiol (OAV: 20?30), 3-mercaporhexyl acetate (OAV: 13?20), beta-damascenone (OAV: 30?57), (E)-2-nonenal (OAV: 9?22), heptanal (OAV: 4?13), hexanal (OAV: 9?12) and 2-isopropyl-3-methoxypyrazine (OAV: 4?14) contributed to the aroma of Lang baijiu. Finally, six compounds (ethyl hexanoate, 2-methyl-3-furanthiol, (E)-2-decenal, guaiacol, 3-mercaporhexyl acetate, and 2-isopropyl-3-methoxypyrazine) with different OAVs were used to determine the effect on the threshold of aromatic reconstitution (AR). It can be seen that ethyl hexanoate, 2-methyl-3-furanthiol, 3-mercaporhexyl acetate, and 2-isopropyl-3-methoxypyrazine could significantly decrease the threshold of AR. The possible reason was that these four compounds had synergistic effects with the aroma compounds in AR. Compared to ethyl hexanoate and 2-methyl-3-furanthiol, the threshold of AR had a slight difference in the presence of (E)-2-decenal in AR. After the addition of guaiacol, the threshold value of AR was significantly increased, indicating a masking effect between guaiacol and the original aroma compounds in AR.
