Abstract

Abstract Comprehensive comparisons of 1 H and 13 C NMR chemical shift values in the furanone cores a, b, and c provide plausible support for a reassessment of the furanone nuclei of the title compounds from b to c. Total syntheses via enantiomerically pure lactic esters were based on the Seebach–Fráter “self-reproduction of stereocenters” methodology. Attachment of the hexadienyl side-chain in a trans, trans-selective manner was achieved ...
