title: A synthesis of 3alpha,6alpha,17alpha-trihydroxy-5beta-pregnan-20-one (triolone) from 3alpha,6alpha-dihydroxy-5beta-pregnan-20-one (diolone).
abstract: An optimization of synthesis of 3alpha,6alpha,17alpha-trihydroxy-5beta-pregnan-20-one from 3alpha,6alpha-dihydroxy-5beta-pregnan-20-one by subsequent acetylenolization, epoxidation, and ring opening reactions has been described. Epoxide hydrolysis at different temperatures (room and at boiling) has also been investigated.
