Monomerine

In a similar manner, the 2-cyano-6-oxazolopiperidine synthon is useful for the chiral synthesis of in-dolizidine (monomerine piperidine [(+)- and (-)-coniine and dihydropinidine] and quinolizidine alkaloids.2-Hydroxymethyl-1-amino-1-cyclopropanecarboxylic acid (-)-(2I )-hydroxy-(3S)-nonylamine and a-substituted phenylethylamines are obtained in optically active form from (-)-N-cyanomethyl-4-phenyloxazolidine.
