Synthesis of Spiro Compounds via Photoisomerisation of Spirodiazirines in the Presence of Alkynes

Selective irradiation of 1,2-diazaspirooct-1-ene (1) in the presence of dimethyl acetylenedicarboxylate (3) yields the spiro-3H-pyrazole 4 via photoisomerisation of 1 to intermediate diazocyclohexane (2) followed by 1,3-dipolar cycloaddition to 3.The strong dipolarophile dimethyl spirooct-1-ene-1,2-dicarboxylate (6), formed by photoelimination of nitrogen from 4, and its reaction products with 2 are obtained as further products.
