Abstract
The boron-mediated aldol reactions of the (Z)-enals 3 and 7 proceed with high levels of 1,4-stereo-induction arising from the gamma-substituent. Reagent control from (+)-Ipc(2)BCl can be used effectively to overturn this substrate bias, thus enabling the stereocontrolled formation of (+)-discodermolide (1) and related analogues 15-18.
