Structure Determination of 8-Benzyl-5-phenyl-3-oxa-4,8-diazatricyclo[5.2.1.02,6]dec-4-ene and 1-(9-Ethoxy-5-phenyl-3-oxa-4,8-diaza-tricyclo[5.2.1.02,6]dec-4-en-8-yl)-ethanone: Their Synthesis, Chemical Relationship and Comparison with Similar Compounds

Abstract

The molecular and crystal structures of 8-benzyl- 5-phenyl-3-oxa-4,8-diaza-tricyclo[5.2.1.02,6]dec-4-ene 11a and 1-(9-ethoxy-5-phenyl-3-oxa-4,8-diaza-tricyclo[5.2.1.02,6] dec-4-en-8-yl)-ethanone 13a have been XRD determined. The compounds crystallize in the monoclinic system with space groups P21/n and P21/c, respectively. The synthesis and chemical relationship between the two compounds are reported and their structures are compared with others of the aza-norbornene and isoxazoline families
