摘要:
Sultones of swing: A sultone served as the key intermediate in the first enantioselective total syntheses of the bioactive title compounds (see scheme), the absolute configuration of which is now established. Starting from 2-bromo-1-(2-furyl)ethanone, 24 steps were required to generate the common basic structure, and in each case two additional steps yielded the natural products.
