X-ray structure analysis of 3,11,17-trioxoandrostane-5α-carbonitrile and of 17α-ethoxycarbonyloxy-3-oxoandrost-4-ene-17-carbonitrile

The crystal and molecular structures of the title compounds were determined by x-ray diffractometric analysis. Torsion angles and puckering parameters are reported for both compounds. In 1 the 5α-cyano group influences the A-ring conformation. The carbonate ester 3 crystallizes in the monoclinic P21 space group with two molecules (I and II) in the asymmetric unit. The D-ring conformation is to some extent different between I and II. (Steroids 57:502–506, 1992)
