Abstract
Based on the synthetic method of optically active 3-alkyl-5-methyl-2(5H)-furanones from lactic acid, two pairs of chiral butenolides 3-tetradecyl- and 3-hexadecyl-5-methyl-2(5H)-furanone have been straightforwardly synthesized from methyl stearate and methyl palmitate respectively by aldol condensation with (R)- or (S)-O-tetrahydropyranyl lactal prepared from corresponding ethyl lactate and beta-elimination.
