Carboxylic acid imides hydrogenolysis

A similar approach towards norbornane carboxylic acid derivatives was developed using pseudoenantiomeric A-acyl-D-galactosyl and D-arabinosyl-oxazolidinones 96 and 97. Reaction with cyclopentadiene under promotion of Me2AlCl, and subsequent hydrogenolysis of the double bond and basic hydrolysis of the imide moiety, furnished the 3-methyl-norbornane-2-carboxylic acids 98 and 99, respectively, in high enantiomeric purity [74,75] (Scheme 10.32). [Pg.457]

Hydrogenolysis of the diallyl alkylmalonate 757 with formic acid in boiling dioxane affords the monocarboxylic acid 758. Allyl ethyl malonates are converted into ethyl carboxylates[471]. The malonic allyl ester TV-allylimide 759 undergoes smooth deallylation in refluxing dioxane to give the simple imide 760(472]. The allyl cyanoacetate 761 undergoes smooth decarboxylation to give... [Pg.394]
