Reaction of 2-Diazopropane and 1,3-Thiazole-5(4H)-thiones

Mloston, Grzegorz,Heimgartner, Heinz

, p. 1825 - 1833 (1992)

At 0 deg C, 1,3-thiazoles 1 and 2-diazopropane in pentane or MeOH undergo a smooth 1,3-dipolar cycloaddition to give spirocyclic 2,4-dihydro-1,3,4-thiadiazoles 6 (Scheme 3).Elimination of N2 occurs already at 20 deg C, yielding spirocyclic thiiranes 7.At
