B-ring aromatization of estrogen derivatives
Hylarides,Wilbur,Mettler Jr.
, p. 657 - 662 (1983)
A noval method of B-ring aromatization of steroid derivatives is reported. Addition of BrCl in methanol to a non-aromatic B-ring double bond results in a rapid double elimination generating the aromatic B-ring. This procedure represents an effective method for conversion of an equilin to an equilenin nucleus.
