2-(2-Bromoallyl)-1,3-dicarbonyl compounds are converted into β-enamino, β-hydrazino esters and ketones, followed by base-promoted cyclization, leading to the formation of the corresponding 1,2,3,5-tetrasubstituted pyrroles. 1,2,4- and 1,2,3,4-Substituted pyrroles are also isolated as minor products. Starting from the 2-(2-bromoallyl)-cyclohexane-1,3-dione the corresponding tetrahydro indolone is prepared in good yield.

3,3-Dimethyl-2-vinyl-1-ethoxycarbonylaziridines were prepared from 2-acylaziridines and phosphoranes, phosphonate or silyl anions.A 3,3-dimethyl-2-ethoxycarbonyl N-vinylaziridine was also prepared.These compounds constitute some analogues of chrysanthemic
