A convenient route to diverse heterocycles through an addition of beta-amino carbonyl compounds to 3-halogeno-4-methoxybenzynes.
[reaction: see text] 3-Halogeno-4-methoxybenzynes 5 generated from 5-(3-halogeno-4-methoxyphenyl)thianthrenium perchlorates 1 and LDA in THF at reflux reacted with various beta-amino carbonyl compounds and 2-aminophenyl benzenesulfonate etc. to give diverse heterocyclic compounds.
