The bicyclo[3.1.0]hexane fragment of the title molecule, C 9 H 12 O 4 , adopts a boat-like conformation, with its methoxycarbonyl substituent in the endo position. In the crystal structure, molecules form centrosymmetric OÐHÁ Á ÁO hydrogen-bonded dimers, which are arranged in layers.
The title novel oxazole derivative, C 8 H 9 N 2 O 3 Br, is formed by displacement of one of the Br atoms in 5,6-dibromo-2,3dihydro-2-methylimidazo[2,1-b]oxazole using metalation followed by reaction with methylcyanoformate. The cyclic moiety in the molecule is slightly bent from a planar con®guratio
