Abstract

Inventia se refera la un procedeu pentru prepararea unor spiro-3-heteroazolone cu formula generala I: (vezi formula) în care 0 reprezinta oxigen, sau azot substituit cu hidrogen sau alchil avînd un numar de la 1 la 4 atomi de carbon; X este hidrogen,brom, clor, iod, o grupare alchil cu un numar de la 1 la 4 atomi de carbon, dimetil si cu conditia ca atunci cînd X este dimetil, n este egal cu unu; Y este hidrogen, halogen, nitro, trifluormetil, o grupare alcoxi avînd un numar de la 1 la 4 atomid e carbon sau o grupare alchil avînd un numar de la 1 la 4 atomi de carbon, cu conditia ca, în cazul în care Y sau Z este nitro, celalalt radical este hidrogen, iar n este 0 sau 1. Procedeul consta în aceea ca, se oxideaza compusul cu formula generalaII: (vezi formula) cu trioxiod de crom în mediu de acid acetic, la temperaturi între temperatura camerei si temperatura de reflux.
