Abstract

Further examples of the occurrence of intramolecular translactonization during condensation of 4-hydroxy-6-methyl-2H-pyran-2-one, 1, or 4-hydroxycoumarin, 4, with carbonyl compounds are desoribed. The structure of previously misassigned products 6a,b is proven by NMR techniques. Application of the HETNOE method to the distinction between structures 9 and 10 is demonstrated. © 1987.
