A convenient stereoselective synthesis of a (−)-vertinolide precursor (original) (raw)

Tetrahedron Letters, 1992

Abstract

Abstract A short practical method for the enantioselective synthesis of (−)-vertinolide precursor 2 is described. The readily available chiral β-alkoxy substituted acrylate 7 has been reacted with the ethyl levulinate to form the tetronic acid nucleus 8, which in three subsequent steps was converted to the known precursor 2 in high overall yield.
