A A -S-ketone will survive this treatment. By contrast, treatment of a 17a, 21-dihydroxy-20-one with zinc-acetic acid produces a 21-acetoxy-20-ketone, probably via a Mattox-Kendall rearrangement (see below)... [Pg.201]

An improved method for the preparation of A" -3-ketones from 4-bromo compounds was described by Mattox and Kendall. This procedure involves dehydrobromination of the 2,4-dinitrophenylhydrazone and subsequent cleavage of the hydrazone with pyruvic acid ... [Pg.288]

Mattox and Kendall have suggested that loss of bromide from the initially formed hydrazone of the a-halo ketone is facilitated by participation of the electron pair on the amine nitrogen atom. The same group has shown that semicarbazones are often superior to 2,4-dinitro-phenylhydra-zones since they can be obtained in higher yields and undergo cleavage more... [Pg.289]
