Heck reaction on 2-bromobenzyloxy-substituted 4H-chromene derivatives using Pd(OAc)2 in Aliquat 336 and N,N-dimethylformamide mixture leads to intramolecular heteroannulation along with hydrolysis, affording chelated 6H-benzo[c]chromen-2-yl ketones. The method offers Pd(0)-catalysis and regioselectivity in product formation. Supplemental materials are available for this article.
