A highly regio- and stereoselective C5 oxyfunctionalization of coprostane steroids by dioxiranes: An improved access to progestogen and androgen hormones.
Coprostane steroids are selectively oxyfunctionalized at C5 by dimethyldioxirane and methyltrifluoromethyldioxirane to give useful intermediates for bioactive compounds.
