Use of biological catalysts for the preparation of chiral molecules. 8. Preparation of propargylic alcohols. Application in the total synthesis of leukotriene B4
摘要:
Leukotriene B4 (LTB4) (1) was synthesized from two chiral propargylic alcohols 2 and 3 obtained by enantioselective enzymatic hydrolysis and enantiogenic microbial reduction, respectively. Condensation of these two synthons using a rapid and reproducible method not involving a Wittig reaction led to a compound with identical biological activity to that of natural LTB4.
