Further Investigations of the Stereochemistry of Electrophilic-Addition Reactions of the Steroidal C-22 Double Bond

Hirano, Yutaka,Takatsuto, Suguru,Ikekawa, Nobuo

, p. 1775 - 1779 (2007/10/02)

Three kinds of electrophilic addition reactions, viz. peracid epoxidation, hydroboration, and iodoacetoxylation, of both the trans- and cis-isomers of 6β-methoxy-3α,5-cyclo-5α-cholest-22-enes (1) and (2) were examined.The observed stereoselectivity can be
