Abstract: (+/-)-4,5,5-Trimethyl-1-pyrroline-1-oxide reacted readily with ethyl 4,5,6,7-tetra-O-acetyl-trans-2,3-dehydro-2,3-dehydro-2,3-dideoxy-L(-)-arabinohepotenoate in anhydrous benzene to give a mixture of two diastereomeric isoxazolidines, [2-alpha,3-beta,3a-alpha,5-alpha]- and [2-alpha,3-beta,3a-alpha,5-beta]-ethyl hexahydro-2-(1,2,3,4- tetraacetoxybutyl)-5,6,6-trimethylpyrrolo[1,2- b] isoxazole-3-carboxylate. The structures and configurations of both diastereomers were determined through the use of the (H-1-H-1) COSY, (C-13-H-1) HETCOR and NOEDS techniques.
