honium borohydride (BTPPB) (1) generated as white solid from benzyltriphenylphosphonium chloride and sodium borohydride is found to be a selective and versatile reducingagent. The reagent in methanol is very useful for reduction of imines, enamines and reductive amination of aldehydes.

Propylamines of the formula (I):
and isomers thereof, particularly those enantiomers and racemates relative to the chiral carbon indicated by an asterisk (*). The propylamines can be used for the treatment of hypertension or angina in humans. A is pyrrolidine, piperidine or morpholine and B is an aromatic heterocycle, aromatic carbocycle or saturated carbocycle, R1, R2 and R3 are lower alkyl groups a optionally joined to form a cycloalkyl or polycyclicalkyl group m is 0 or 1; Y is halo, alkyl, alkoxy, trifluoromethyl, hydroxy, or methylenedioxy; n is 0, 1, or 3.
