σ-Complexes in the pyrimidine series. 13. Reaction of 7- and 5-methoxyfuroxano[3,4-<i>d</i>]pyrimidines with some C-nucleophiles

Abstract

We have studied the reaction of isomeric 7-and 5-methoxyfuroxano[3,4-d]pyrimidines with carbanions of some CH acids. We have shown that regardless of the position of the substituent in the pyrimidine ring, nucleophilic attack occurs regioselectively at the C₍₇₎ atom. As a result, we have obtained the products of substitution at the methoxy group, and also anionic σ complexes and covalent σ adducts.
