実験手順

(1S,1aR,7bS)-4,7-difluoro-1,1a,2,7b-tetrahydrocyclopropa[c]chromene-1-carboxylic acid (50 mg, 0.22 mmol, ee ˜90%) was mixed with toluene (1 ml), triethylamine (0.034 ml, 1.1 eq), 4-aminopyrimidine (25 mg, 1.1 eq), DPPA (0.054 ml, 1.1 eq). The reaction mixture was then heated with stirring at 110° C. for 3 h. The reaction mixture was concentrated by rotary evaporation and the product was crystallized from ethanol and collected by filtration to give 20 mg of the product as white solid.
