✦ Synopsis


The reaction of dibenzalcyclohexanone with hydroxylamine hydrochloride affords three compounds: the oxime of 2-benzylidenecyclohexanone (Z), 3-phenyl-7-benzylidene-3,3a,4,5,6,7-hexahydr~2,l-ben~soxazole (3) and 3-phenyl-3,3a,4,5,6,7-hexahydro-2,l-ben~soxazol~7~pir~~~~-phenylaziridine) (4). Their structures were deduced by 2D NMR analysis. Single-crystal x-ray diffraction was used to confirm the structure and stereochemistry of 4. A possible mechanism for this reaction is proposed.
