Amat, Mercedes,Llor, Nuria,Bosch, Joan
, p. 2223 - 2226 (1994)
The preparation of chiral cis- and trans-oxazolopiperidones 1, 2, and 3 by alternative procedures and an efficient synthesis of the piperidine alkaloid (R)-(-)-coniine from trans-1 is reported.
A NEW POTENTIAL ACYL IMINIUM ION FOR THE ASYMMETIRIC SYNTHESIS OF PIPERIDINE DERIVATIVES
Royer, Jacques,Husson, Henri-Phillipe
, p. 1493 - 1496 (2007/10/02)
Epimeric oxazolopiperidones (1a) and (1b) were prepared independently, both from R-(-)-phenylglycinol as starting material.They represent chiral potential iminium ions.
