Chiral 2-Methyl-2-phenyl-1,3-oxazine-4,6-diones. Novel Building Blocks for the Synthesis of Enantiomerically Pure Compounds

Synthesis and optical resolution of (Z)-5-benzylidene as well as 5-alkyl derivatives of the title compounds have been accomplished.The Diels-Alder reaction of the former with ketene diethylacetal and base-mediated methylation of the latters were found to
