Enantioselective total synthesis of (+)-labd-8(17)-ene-3β,15-diol and (−)-labd-8(17)-ene-3β,7α,15-triol
摘要:
Enantioselective total synthesis of the labdane diterpenes (+)-labd-8(17)-ene-3 beta,15-diol ((+)-1) and (-)-labd-8(17)-ene-3 beta,7 alpha, 15-triol ((-)-2) was achieved starting from the (S)-(+)-enantiomer of the Wieland-Miescher ketone (+)-3 and the (R)-(+)-enantiomer of lactone (+)-13. These results established that the natural compounds (+)-1 and (-)-2 possess the (13S) absolute configuration. (C) 1997 Published by Elsevier Science Ltd.

bearing an electron‐withdrawing group, for example, a carbonyl group. This asymmetricreduction has been exploited for biocatalysis. Going beyond its canonical function, we show that members of this enzyme family can also catalyze the formation of C−C bonds. α,β‐Unsaturated aldehydes and ketones containing an additional electrophilic group undergo reductive cyclization. Mechanistically, the two‐electron‐reduced
