The reaction of cis-2-methoxy-4-methyl-1,3-dioxane (4) with Grignard reagents proceeds in a totally regioselective manner via rupture of the less congested C(2)-0(1) bond remote from the 4-methyl substituent. The analogous r-2-methoxy-cis-4,cis-6-dimethyi-l,3dioxane (2) is totally inert to the acti
The stereoelectronically controlled reaction of P-methoxy-1,3-dioxane (1) with Grignard reagents does not follow the course suggested by the behavior of anancomeric models for the conformational isomers of 1. Treatment of 1 with RMgX leads to the predominant formation of acid labile 3-(l'-methoxyalk
