N-acyliminium ions, which undergo the nucleophilic addition of trimethylsilyl cyanide (TMSCN) to provide the N-protected α-aminonitriles in very good yield. A variety of α-amido p-tolylsulfones were prepared from aromatic as well as aliphatic aldehydes for the synthesis of α-aminonitriles.
A simple and convenient method for the direct, aminocatalytic, and highly enantioselective Mannich reactions of aldehydes with in situ generated N‐carbamoyl imines has been developed. Both α‐imino esters and aromatic imines serve as suitable electrophilic components. Moreover, the judicious selection of commercially available secondary amine catalysts allows selective access to the desired stereoisomer

A general one-pot synthesis of substituted 2-aminoethylidene-1,1-bisphosphonates has been developed. The protocol involves base-induced addition of sodium tetraethyl methylenebisphosphonate to N-Boc imines generated in situ from N-Boc-alpha-amidoalkyl-p-tolylsulfones by the action of sodium hydride. The direct and efficient conversion of the title compounds into aza-Morita-Baylis-Hillman-type adducts has been also elaborated. (c) 2007 Elsevier Ltd. All rights reserved.
