mines undergo facile aza-Morita-Baylis-Hillman reactions with penta-2,4-dienenitrile in anhydrous DMF in the presence of catalytic 3-hydroxyquinuclidine and methanol to afford the corresponding unsaturated aminonitriles.

were obtained as essentially pure E-isomers. Cyclization of the E-isomers of the products derived from the dienylsulfone 3 and the dienoate ester 6 occurred via intramolecular conjugate addition under base-catalyzed conditions to afford functionalized piperidines 5 and 16, respectively. The aza-Morita−Baylis−Hillman reaction and subsequent cyclization of the imine 2a with 3 were also carried out as
Novel bleaches, a method for bleaching substrates using these materials and detergent compositions containing same are reported. The bleaches are of the N-sulfonyloxaziridine type. Substrates such as fabrics may be bleached in an aqueous solution containing the oxaziridine.
