The Diels–Alder reaction of enantiomerically pure (E)-γ-keto-α,β-unsaturated p-tolylsulphoxides 3 with cyclopentadiene give four easily separable diastereomers. The effect of several Lewis acids on the reaction was studied, finding a high endo s

The preparation of both isomers at sulphur of N -(benzyloxycarbonyl)- S -methyl (-propyl)- S -oxo- l -cysteine methyl ester has been carried out using l -cysteine and diacetone- d -glucose (DAG) as starting material and inductor of the chirality at s
