Treatment of arylmethylideneamines with 5-chloropentanoyl chloride in benzene in the presence of 2,6-lutidine afforded novel trans-4-aryl-3-(3-chloropropyl)azetidin-2-ones in good yields. The latter 3-(3-chloropropyl)-β-lactams were transformed selectively into trans-methyl 1-alkyl-2-arylpiperidine-3-carboxylates in high yields and purity upon subsequent treatment with hydrogen chloride in methanol

A new palladium-catalyzed synthesis of 3-amido-substituted beta-lactams is reported. This process involves the one-pot coupling of four components, imines, carbonmonoxide, and acidchloride, providing a flexible route to construct this class of heterocycle. The generation of beta-lactams with two different imines can also be accomplished, providing a method to assemble these products with independent

Samariumdiiodide in the presence of a catalytic amount of nickel diiodidemediates a very fast dimerization of imines into vicinal diamines and the mixed coupling of imines and ketones to give β-amino alcohols.

Cycloaddition of diethyl 1-diazomethylphosphonate onto a CN double bond is described. It was found that the reaction of this phosphorus diazomethane with benzylidene-alkyl-amines resulted in the formation of (1-alkyl-5-phenyl-4,5-dihydro-1H-[1,2,3]triazol-4-yl)-phosphonic acid diethyl esters, whereas its reaction with methylene-aryl-amines, generated from the corresponding hexahydro-1,3,5-triazines
