Enantioselective Syntheses of Ring-C Precursors of Vit. B12. Reagent Control
摘要:
[GRAPHICS]Enelactones of the general structure S-(-)-I were prepared in three steps from alcohol 21 and acids 22 (ee approximate to 85%). Lactones S-(-)-I are versatile precursors to enelactams II of the type found in Vitamin B-12.
