This work describes the synthesis of 2-iodo-3,4,5-trimethoxybenzoic acid. The combination of iodine and silver trifluoroacetate (AgTFA) reagents was used successfully for the iodination of 3,4,5-trimetoxybenzoic acid. To improve the efficiency of the synt
Total Synthesis of (+)-Isoschizandrin Utilizing a Samarium(II) Iodide-Promoted 8-Endo Ketyl-Olefin Cyclization

The 13-step synthesis of (+)-isoschizandrin reported herein features a samarium(II) iodide-promoted 8-endo ketyl-olefin coupling to assemble the eight-membered ring present in the target concomitantly with the required functionality and stereochemistry. In constructing (+)-isoschizandrin as a single atropisomer, the synthesis utilizes a kinetic resolution of a seven-membered lactone using a CBS-oxazaborolidine.
Synthesis of 3,4-O-(3,3',4,4',5,5'-Hexamethoxydiphenoyl)-L-arabinopyranose

3,4-O-(3,3',4,4',5,5'-Hexamethoxydiphenoyl)-L-arabinopyranose (Ib) has been synthesized by condensation of 1-O-(3,4,5-tri-O-methylgalloyl)-L-arabinose (IV) with hexamethoxydiphenoyl chloride (IIIb) in pyridine in the presence of triethylamine and subsequent removal of the protecting galloyl group.The synthetic Ib has been found to be identical (m.m.p., co-TLC, IR) with methyl ether of the natural 3,4-O-(3,3',4,4',5,5'-hexahydroxyphenoyl)-L-arabinopyranose (Ia).
