Total syntheses of macrosphelides (+)-A, ()-A and (+)-E
摘要:
Total syntheses of (+)-macrosphelide A 1 (18.5% overall yield in 11 steps) and (+)-macrosphelide E 2 (23.9% overall yield in 11 steps) have been achieved via the chemoenzymatic reaction product (4 R,5 S)-4-benzyloxy-5-hydroxy-2( E)-hexenoate 4. The enantiomer (−)-A ( 1) (14.2% overall yield in 11 steps) of (+)- 1 was also synthesized from the chemoenzymatic reaction product (4 S,5 R)-4-benzyloxy-5-hydroxy-2( E)-hexenoate 4.
