Abstract
The structure of ethyl 5-methyl- 10-(2,4,6-trimethylphenyl)-8-oxa-1,2,9-triazabicyclo[5.3.0]deca-3,5,9-triene-2-carboxylate (I) has been determined. The 1,2-diazepine ring has a twisted-sofa form and the 1,2,4-oxadiazole ring has an envelope conformation, with the bridgehead C7 atom out of the plane of the ring. The terminal methyl group of the side chain is disordered, being split over two different positions
