The α and β-diastereomers of 4,5-epoxy-cholestan-3-one were obtained by epoxidation of cholest-4-en-3-one with HO in basic media. The α-diastereomer 2a shows a monoclinic crystal system with dimension of cell unit: a = 11.6088(15), b = 6.3272(8), c = 16.164(2) Å; β = 94.040(11)° and trans A/B, B/C and C/D ring junctions and the β-diastereomer 2b has a orthorhombic crystal system with dimension of cell unit: a = 9.0542(4), b = 10.6737(5), c = 24.9723(9) Å and cis A/B, trans B/C and trans C/D rings junctions. Graphical Abstract: The crystal structures of 4,5-epoxy-5α-cholestan-3-one ( 2a) and 4,5-epoxy-5β-cholestan-3-one ( 2b) are described.[Figure not available: see fulltext.] [ABSTRACT FROM AUTHOR] |
