Antenna-initiated photochemistry in polyfunctional steroids. photoepimerization of 3α-(dimethylphenylsiloxy)-5α-androstane-6,17-dione and its 3β isomer by through-bond exchange energy transfer

Wu, Zheng-Zhi,Nash, John,Morrison, Harry

, p. 6640 - 6648 (2007/10/02)

We have previously reported that photolysis of 3α-(dimethylphenylsiloxy-5α-androstane-11,17-dione, in the presence of triethylamine (TEA) and with 266-nm light so as to selectively excite the dimethylphenylsiloxy (DPS) "antenna", primarily gives rise to t
