Synthetic routes are described toward the preparation of α- as well as β-substituted aminoethanesulfinyl chlorides, starting from either an aldehyde or from an amino acid derivative.The sulfinyl chlorides are used as building blocks for the preparation of homochiral α- or β-substituted sulfinamide and sulfonamide transition-state isosteres.The methodology has been applied to the synthesis of peptidosulfonamide peptidomimetics such as a hapten needed for the generation of antibodies and potential HIV protease inhibitors.In addition, the β-substituted aminoethanesulfinyl chlorides were used as building blocks for the preparation of a tetrapeptidosulfonamide, which can be considered as a biopolymer mimetic, employing a repetition of a cycle of three reactions: coupling of the sulfinyl chloride to the N-terminus of the growing peptidosulfonamide, oxidation to the sulfonamide, and deprotection of the N-terminus.
