High-pressure mercury lamp irradiation of chiral alkyl glyoxylates [R(−)-menthyl,R(−)- andS(+)-2-octyl,R(−)-andS(+)-2, 2-dimethyl-3-butyl] with furan led to alkyl 2,7-dioxabicyclo-[3.2.0] hept-3-ene-6-car☐ylates (13a–e) exhibiting low (2.5–7.3%) optical purity. Compounds13a–e were isomerized to alkyl 3-furylglycolates (14a–e) in good yield. ConfigurationS was assigned to levorotary methyl 3-furlymethoxyacetate

A method for the preparation of 3-substitutedfurans starting with the addition of bis(phenylthio)methyllithium to an ester, followed by a sequence consisting of a Wittig reaction, a DIBAL-H reduction and an iodine-mediated cyclization is described.
