A series of O,O-dialkyl-α-(p-toluenesulphonamido)benzyl phosphonates have been synthesised by the addition of alkyl phosphites to N-benzylidene-p-toluenesulphonamide.The compounds exhibit chemical shift nonequivalence of prochiral alkoxy groups.Furthermore, on the basis of observed 2JPCH, a preferred conformation with benzylic hydrogen in gauche-disposition to phosphoryl group has been suggested.
