ChemInform Abstract: SYNTHETIC STUDIES OF LAURENCIN AND RELATED COMPOUNDS. V. TRANSFORMATION OF CIS-2-ETHYL-8-FORMYL-3,4,7,8-DIHYDRO-2H-OXOCIN-3-ONE 3-ETHYLENE ACETAL INTO (.+-.)-LAURENCIN

Transformation of the title starting material into (±)-laurencin, which implies synthesis of the natural product, is described. The structure and configuration of synthetic intermediates are defined on the basis of the spectral evidence.
