NEW STRATEGY FOR RACEMIZATION OF 2-AMINO-1,3-PROPANEDIOLS, KEY INTERMEDIATES FOR THE SYNTHESIS OF ANTIBIOTIC DRUGS
Giordano, Claudio,Cavicchioli, Silvia,Levi, Silvio,Villa, Marco
, p. 5561 - 5564 (2007/10/02)
A new strategy for racemization of the 2-amino-1,3-propanediol 2b, based on a chemoselective oxazoline ring formation and a highly diastereoselective reduction of the ketone 4 is reported.
