New methodology for the synthesis of enantiopure (3R,2aR)-(-)-3-phenyl-hexahydro-oxazolo[3,2-a]-pyridin-5-one: A synthesis of (S)-(+)-coniine

Teran,Gnecco,Galindo,Juarez,Bernes,Enriquez

, p. 357 - 360 (2001)

A new and efficient methodology for the enantiopure synthesis of (3R,2aR)-(-)-3-phenyl-hexahydro-oxazolo[3,2-a]pyridin-5-one 3 starting from (1′R)-(-)-1-(2′-hydroxy-1′-phenyl-ethyl)-(1H)-pyridin-2-one 1 is described. In addition, the enantiospecific synthesis of (S)-(+)-coniine hydrochloride 6 in good yield from 3 is reported.
