Carbon transfer reactions with heterocycles-IV : Synthetic equivalence of perhydrooxazines with carbonyl compounds. A facile synthesis of streptindole and analogues

Abstract

Oxazolidines and tetrahydro-(2H)-1,3-oxazines transfer their C(2) units at the carbonyl group oxidation level to indoles and provide diindolylmethane derivatives. 2-Acetoxymethyl-4,4,6-trimethyltetrahydro-(2H)-1,3-oxazine and indole give streptindole.
