Asymmetric Synthesis of the Northern Half C1−C16 of the Bryostatins

Asymmetric Synthesis of the Northern Half C1−C16 of the Bryostatins

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 mani...

Fragment coupling by dithiane strategy and protecting group manipulations provided an advanced chemodifferentiated northern half segment.
