The configuration of some decalin spiro-hydantoins and amino-acids
Abstract
Several decalin spiro-hydantoins and amino-acids have been prepared. Their configurations have been determined by deamination experiments, measurements of dissociation constants, and i.r. and n.m.r. spectra. The configurations are the opposite to those previously assigned to the alkyl amino-cyclohexane-carboxylic acids.
