A series of (trimethylstanny1)-and (chlorodimethylstanny1) propyl derivatives having the carboxymethyl functional group has been prepared via free radical additions of trimethyltin hydride and dimethyltin chlorohydride to methyl (E)-2, 3-disubstituted propenoates giving high yields of mixtures of diastereomeric products. The relationship between the diastereomers obtained in both reactions is demonstrated by quantitative conversion of ...
