Unprecedented cholestane analogs have been synthesized by Diels-Alder reactions between a diene generated in high yields from vitamin D3 and appropriate dienophiles. This strategy is useful for the scarcely utilized A+CD → ABCD approach to the tetracyclic steroid nucleus.

Abstract
Unprecedented cholestane analogs have been synthesized by Diels-Alder reactions between a diene generated in high yields from vitamin D3 and appropriate dienophiles. This strategy is useful for the scarcely utilized A+CD → ABCD approach to the tetracyclic steroid nucleus.File in questo prodotto:
