摘要

Abstract Piperidine reacts with 3-bromo-3-buten-2-one to give a mixture of 3, 4- dipiperidinobutan-2-one and 3-piperidino-3-buten-2-one. The latter is also formed by the action of a strong base (Et 3 N in THF or MeONa in MeOH) on the dipiperidino derivative. Analogous reaction of 2-bromo-3-phenylpropenal with N-methylaniline affords 2-[methyl (phenyl) amino]-3-phenylpropenal which is the first captodative formyl (amino) alkene ...
