5α-Androst-3-en-17β-yl acetate

In the crystal structure of the title compound, C(21)H(32)O(2), ring A is highly distorted, with a conformation inter­mediate between 10β-sofa and 1α,10β-half chair; rings B and C have slightly flattened chair conformations. Ring D assumes an unusual 13β-envelope conformation, probably induced by th...

description In the crystal structure of the title compound, C(21)H(32)O(2), ring A is highly distorted, with a conformation inter­mediate between 10β-sofa and 1α,10β-half chair; rings B and C have slightly flattened chair conformations. Ring D assumes an unusual 13β-envelope conformation, probably induced by the acet­oxy substituent. Cohesion of the crystal structure is due only to weak van der Waals inter­actions.
