Synthesis of An Unusual Tetrahydrofuro[3,4-D] Oxazole Ring System

ABSTRACT

Treatment of methyl 3-amino-3-deoxy-5,6-O-isopropylidene-β-D-allofuranoside, prepared in four steps from diacetone-D-glucose, with N,N-dimethylformamide dimethyl acetal resulted in the formation of a novel bicyclic tetrahydrofuro[3,4-d]oxazole ring system.
