ON THE STEREOCHEMICAL ASPECTS OF THE 1,1-CYCLOADDITION REACTION OF DIAZOALKENES

Allyl substituted diazoalkenes undergo intramolecular 1,1-cycloaddition with complete retention of configuration to give 1,2-diazabicyclohex-2-enes.

An unusual example of a 1,1-cycloaddition reaction of a diazoalkane

Thermolysis of the sodium salt of E-1,4-diphenyl-3-buten-1-one N-tosylhydrazone gave rise to the corresponding diazoalkane which undergoes a subsequent 1,1-cycloaddition reaction to produce 3,6-diphenyl-1,2-diazabicyclo[3.1.0]hex-2-ene.
