Asymmetric Synthesis of the Northern Half C1−C16 of the Bryostatins
摘要:
[GRAPHICS]Starting from 8-oxabicyclo[3.2.1]oct-6-en-3-one and racemic 2,2-dimethyl-8-oxabicyclo[3.2.1]oct-6-en-3-one the C1-C16 segment of the bryostatins has been synthesized in 30 steps and 9% overall yield (17 steps longest linear sequence), Fragment coupling by dithiane strategy and protecting group manipulations provided an advanced chemodifferentiated northern half segment.

The C(10)C(16) segment of the bryostatins has been synthesized (12 steps, 15 % overall yield) and a cyanohydrin based strategy was developed for coupling with a C(1)C(9) model.
