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.

An efficient total synthesis of leukotriene B<sub>4</sub>
attracted great interest from scientists within the chemical, medicinal, and pharmaceutical research community. One such example is leukotriene B4 which has been the subject of many pharmacological studies. Herein, we report a convergent and stereoselective synthesis of this potent lipid mediator in 5% yield over 10 steps in the longest linear sequence from commercial starting materials. The key steps were
