Ethyl 7-(hydroxyimino)cyclopropa[b]chromen-1a-carboxylate and their derivatives have been synthesized through directed acylation, intramolecular cyclization under the catalysis of iodine, cyclopropanation, esterification and oximation by using phenol and maleic anhydride as starting materials. In the current invetigation, the construction of chromone scaffold was improved and the cyclopropanation upon the treatment of Corey's dimethyloxosulfonium methylide was applied. The structures of all the intermediates and final products were confirmed by 1H NMR, 13C NMR, and MS, respectively. The overall yields of these 5-step procedures were 20.1%~29.5%.
Key words: mGluR modulators; total synthesis; iodonium; cyclopropanation
