The rhodiumcatalysed reactions of N-allyl- and N-butenyl-1,3-diaminopropanes give single products arising from exclusive hydroformylation at the terminal carbon when the hindered bisphosphite ligand, BIPHEPHOS is used. Reactions using a high carbon monoxide: hydrogen ratio (9:1) and triphenylphosphine as ligand give predominantly lactams arising from carbonylation but with poor control of regioselectivity
A compound represented by general formula (I) and a pharmacologically acceptable salt thereof, reduced in the adverse effect against the extrapyramidal system and hence useful as an antipsychotic agent with few side effects.
