Reaction Conditions

Reaction Steps

Under argon atmosphere, to a solution of N-[2-(tert-butyldimethylsilanyloxymethyl)allyl]-2-diazo-N-(2,4-dimethoxybenzyl)acetamide (43 mg) in benzotrifluoride (0.4 ml) was added rhodium (II) acetate dimer dihydrate (2.4 mg) at room temperature, and the mixture was stirred at 50° C. for 24 hours. This reaction mixture was concentrated under reduced pressure, the resulting residue was purified by silica gel column chromatography (eluent: n-hexane/ethyl acetate=2/1) to give the titled compound (14.2 mg).
