Two new types of conformationally restricted S-phenylcysteine are presented. The restriction comprises a cyclobutane unit that includes the α- and β-carbons of the α-amino acid. The synthetic strategy is based on a formal [2+2] cycloaddition between 2-(acylamino)acrylates as acceptor alkenes and vinyl sulfides as donor alkenes, promoted by aluminum-derived bulky Lewis acids. © Georg Thieme Verlag Stuttgart.
