First total synthesis of prionoid E, A bioactive rearranged secoabietane diterpene quinone from Salvia prionitis

The first total synthesis of prionoid E (1), a rearranged secoabietane diterpene quinone isolated from Salvia prionitis, was achieved efficiently by means of Wacker oxidation (Scheme 5) and aldol condensation (Scheme 7) as the key steps in the synthetic sequence. Thus 1 was prepared in 15 steps in 3.7% yield starting on one hand from anisole (=methoxybenzene) and methylsuccinic anhydride (=dihydro-3-methylfuran-2,5-dione) via 4 (Scheme 3 and 5), and on the other hand from 2-hydroxy-2-methylpropanoic acid via 5 (Scheme 6).

Enantioselective hydrogenation of alpha-ketoesters over alkaloid-modified platinum nanowires

A green process for enantioselective hydrogenation of alpha-ketoesters over cinchona alkaloid-modified platinum (Pt) nanowires has been developed. Pt nanowires with a diameter of ?1 nm were successfully synthesized, and used for the asymmetric hydrogenation of alpha-ketoesters in the presence of cinchona alkaloids under a low pressure at room temperature in water. Quantitative yields and excellent enantioselectivity of up to 78% were achieved. The catalyst along with the modifier was recycled multiple times without any significant loss in activity or selectivity. To our knowledge, such a catalyst system is unprecedented for asymmetric hydrogenation of alpha-ketoesters. The Royal Society of Chemistry.

Quorum quenching: Role in nature and applied developments

Quorum sensing (QS) refers to the capacity of bacteria to monitor their population density and regulate gene expression accordingly: the QS-regulated processes deal with multicellular behaviors (e.g. growth and development of biofilm), horizontal gene transfer and host-microbe (symbiosis and pathogenesis) and microbe-microbe interactions. QS signaling requires the synthesis, exchange and perception of bacterial compounds, called autoinducers or QS signals (e.g. N-acylhomoserine lactones). The disruption of QS signaling, also termed quorum quenching (QQ), encompasses very diverse phenomena and mechanisms which are presented and discussed in this review. First, we surveyed the QS-signal diversity and QS-associated responses for a better understanding of the targets of the QQ phenomena that organisms have naturally evolved and are currently actively investigated in applied perspectives. Next the mechanisms, targets and molecular actors associated with QS interference are presented, with a special emphasis on the description of natural QQ enzymes and chemicals acting as QS inhibitors. Selected QQ paradigms are detailed to exemplify the mechanisms and biological roles of QS inhibition in microbe-microbe and host-microbe interactions. Finally, some QQ strategies are presented as promising tools in different fields such as medicine, aquaculture, crop production and anti-biofouling area.

Haem d1: Development of a new coupling procedure leading to the synthesis of isobacteriochlorins

A new approach has been developed for construction of the western and eastern lactams, e.g. 2 and 3, needed for synthesis of isobacteriochlorins. It involves acylation of pyrroles with lactonic acids to form ketones. These are then efficiently converted into the desired lactams by a short sequence of reactions. All the steps are high yielding and simple to carry out.

Catalytic carbonylation of beta-lactones to succinic anhydrides

A well-defined,highly active and selective catalyst for the synthesis of succinic anhydrides from CO and beta-lactones is reported. At 200 psi of CO, the catalyst [(N,N?-bis(3,5-di-tert-butylsalicylidene)phenylenediamino)Al(THF)2][Co(CO)4] carbonylates beta-propiolactones to succinic anhydrides in high yield. (R)-beta-Butyrolactone is carbonylated to (S)-methylsuccinic anhydride with clean inversion of stereochemistry, while cis-2,3-dimethyl-beta-propiolactone yields exclusively trans-2,3-dimethylsuccinic anhydride. These data are consistent with a mechanism involving nucleophilic attack by [Co(CO)4]- on the beta carbon of the lactone, followed by CO insertion and anhydride formation. Copyright
