  • Highly enantioselective preparation of C2-symmetrical diols: microbial hydrolysis of cyclic carbonates
    作者:Kazutsugu Matsumoto、Youichi Sato、Megumi Shimojo、Minoru Hatanaka
    DOI:10.1016/s0957-4166(00)00144-0
    日期:2000.5
    A new type of microbial enantioselective hydrolysis of C-2-symmetrical cyclic carbonates is disclosed. During the screening test of the five-membered substrate (4,5-dimethyl-1,3-dioxolan-2-one 5), Pseudomonas diminuta was selected as the best strain to perform the stereoselective hydrolysis. The reaction of dl-5 with this microorganism in aqueous media containing THF as the co-solvent afforded (S,S)-5 and (R,R)-butanediol 1 in excellent yields. It was found that the ring size did not affect the reactivity and enantioselectivity although the enzyme had a high substrate specificity for the side chain. A six-membered cyclic carbonate, dl-4,6-dimethyl-1,3-dioxan-2-one 6, was smoothly hydrolyzed with higher enantioselectivity to afford the optically active (S,S)-6 and (R,R)-2,4-pentanediol 2.

  • Mechanism-guided design of flow systems for multicomponent reactions: conversion of CO2 and olefins to cyclic carbonates
    作者:Jie Wu、Jennifer A. Kozak、Fritz Simeon、T. Alan Hatton、Timothy F. Jamison
    DOI:10.1039/c3sc53422g
    日期:——
    multi-step flow system enabled an efficient general process for the synthesis of cyclic carbonates from alkenes and CO2. The flow system proved to be an ideal platform for multicomponent reactions because it was straightforward to introduce reagents at specific stages without their interacting with each other or with reaction intermediates prone to destruction by them. This system exhibited superior
