Semi-catalytic reduction of secondary amides to imines and aldehydes

Secondary amides can be reduced by silane HSiMe2Ph into imines and aldehydes by a two-stage process involving prior conversion of amides into iminoyl chlorides followed by catalytic reduction mediated by the ruthenium complex [Cp(i-Pr3P)Ru(NCCH3)2]PF6 (1). Alkyl and aryl amides bearing halogen, ketone, and ester groups were converted with moderate to good yields under mild reaction conditions to the corresponding imines and aldehydes. This procedure does not work for substrates bearing the nitro-group and fails for heteroaromatic amides. In the case of cyano substituted amides, the cyano group is reduced to imine.

Some bicyclic C-fused chlorinated tetrahydrofuro[3,2-c]azetidin-2-ones were prepared by a fairly general route involving Staudinger reaction of allylic/propargylic imidates with dichloroketene followed by highly diastereoselective CuCl/PMDETA-catalyzed 5-
The Reaction between Cyanide Ion and Nitrones; a Novel Imidazole Synthesis

By contrast with the CN-diphenylnitrones, cold aqueous ethanolic potassium cyanide converts N-methyl-C-phenylnitrone into 1-methyl-4,5-diphenylimidazole.The scope of this reaction has been investigated, and shown to proceed via intermediate cyano-imines, some of which have been synthesised by alternative routes.
