Methylmagnesium carbonate ketone reactions

An earlier series of experiments established useful synthetic transformations involving carboxylation of ketones and nitroalkanes to yield P-keto acids and a-nitro acids respectively (Scheme 94).362 363 The reagent is methylmagnesium carbonate and the intermediate (130) can be alkylated with concomitant decarboxylation to provide greater versatility. These reactions can also be extended to ketone functions in imidazoline- and oxazolidine-diones (Scheme 95).364,365... [Pg.216]

Reaction of 17j -acetoxy-3,3-ethylenedioxy-5a-androstan-l-one (1) with methylmagnesium bromide followed by treatment with acid and reacetylation affords the 1-methyl-A -3-ketone (3). The configuration of carbon-1 of the intermediate (2) has not been established/ ... [Pg.56]
