A FAVORSKI REACTION USING IODOSOBENZENE
Daum, Sol J.
, p. 4725 - 4728 (2007/10/02)
Iodosobenzene or iodobenzene diacetate and excess base when reacted with 17β-hydroxy-5α-androstane-3-one (1a) unexpectedly gave a good yield of Favorski acid (3a) and some (3b). 17β-hydroxy-5α-19-norandrostan-3-one (1b) gave mainly the expected dimethylketal of the 2α-hydroxy-3-ketosteroid (5).
