Etude de la synthese de dialkyl-2,4 acylamino-5 oxazoles par cyclisation a partir d'α-cyanoalkylamides d'acides, de N-acetyl α-aminoamides ou de dipeptides. Fonctionnalisation des oxazoles obtenus
The invention is novel intermediates useful in producing taxol. These include the oxazolidine ester (III) ##STR1## the oxazolidine acid (IV) ##STR2## and the oxazolidine (XI) ##STR3##
