Stereoselectivity in the Addition of 1,3-Dipolarophiles to 6-Aryl-1,5-diazabicyclo[3.1.0]hexanes
摘要:
Thermolysis of 6-aryl-1,5-diazabicyclo[3.1.0]hexanes in the presence of N-arylmaleimides having a substituent in the ortho position of the aromatic ring leads to predominant formation of the corresponding trans-9-arylperhydropyrazolo[1,2-a]pyrrolo[3,4-c]pyrazole-1,3-diones. 6-Aryl-1,5-diazabicyclo[3.1.0]hexanes react with fumaric acid derivatives in a stereoselective fashion, affording perhydropyrazolo[1,2-a]pyrazoles with a trans,trans configuration.
