Stereoselectivity of Cydoaddition of<i>N</i>-(Cyanomethyl)- and<i>N</i>-(α-Cyanobenzyl)imines with Olefinic Dipolarophiles. Synthetic Equivalents of Nitrile Ylide 1,3-Dipoles
N-(Cyanomethyl)- and N-(α-cyanobenzyl)imines derived from a variety of aldehydes and ketones can tautomerize into N-protonated azomethine ylides which undergo cycloadditions with olefinic dipolarophiles. These cycloadditions are often accompanied by the elimination of HCN, mostly in a stereospecific manner, showing these imines to be synthetic equivalents of nonstabilized nitrile ylides.

Functionalized ketimines of the general formula RR'C(=NCH2Y) [R and R' = Ph, alkyl; Y = CN (1), CH2Cl (2), COOMe (3)] have been prepared by the condensation of ketones with the corresponding primary amine hydrochloride salts [NH2CH2CN.HCl (4), NH2CH2CH2Cl.HCl (5) and NH2CH2COOMe.HCl (6), respectively]. The reported reaction proceeds mildly in a single step without the need of a previous isolation of the free amine from its salt. N,N-Dimethylformamide (DMF) is used as the solvent and TiCl4 as the drying agent.
