Abstract

The reactions of bromozinc enolate reagents on formylcoumarins (1, 2) afforded spiro-γ- lactones (15-18), furan derivatives (13, 14), and coumarinylcarbinols (3, 4) as highly unusual products along with the expected β-hydroxyesters (5-12). Stereochemical features of some of these products turned out to be highly informative and were unambiguously corroborated. Key words: formylcoumarins, unusual Reformatsky products, stereochemistry.
