(Chemical Equation Presented). Full details of two versions of the total synthesis of epoxyquinols A, B, and C and epoxytwinol A (RKB-3564D) are described. In the first-generation synthesis, the HfCL4-mediated diastereoselective Diels-Alder rea

A practical total synthesis of both enantiomers of epoxyquinols A and B has been developed. Key reactions are the chromatography-free preparation of an iodolactone by using acryloyl chloride as dienophile in the Diels-Alder reaction of furan, the lipase-mediated kinetic resolution of a cyclohexenol derivative, and a modified procedure for α-iodonation of a cyclohexenone.

(3R)-and (3S)-Fluoro-(4R,5R)-dihydroxy-1-cyclohexene-1-carboxylic acids (the (3R)- and (3S)-fluoro analogues of (-)-shikimic acid) have been synthesised from (-)-shikimic acid via an intermediate epoxide (a fungal metabolite from Chalara microspora) that
