Abstract:Methyl 5-oxo-7-(trimethylsilyl)hept-6-ynoate(4)was synthesized by the reaction of dihydro-2H-pyran-2,6(3H)-dione(1)with 1,2-bis(trimethylsilyl)ethyne, followed by esterification with methanol. The title compound 5 with 98% ee in an overall yield of 64% was synthesized by the reduction of 4 using novel Noyori reagent. The structures of the product and all key intermediates were characterized by 1H NMR and MS spectra. Reaction conditions were optimized including the type of catalysts, reaction temperature and amount of chemicals.
Key words:dihydro-2H-pyran-2,6(3H)-dione;(S)-methyl 5-hydroxy-7-(trimethylsilyl)hept-6-ynoate; reducing agent
