| Abstract | The title compds. II [R-H, benzyloxycarbonyl; Y=OH, amino! were prepd. Thus, 6.9g S-b-fluoro-4-(benzyloxycarbonylamino) chroman-4- carboxylic acid in 100ml methanol was mixed with 0.5g 5%-Pd/c and then the resulting mixt. was treated with hydrogen at 4 atm for 2-3h. The catalyst was removed. The resulting soln. was concd. and treated with toluene to give 3.9g S-b-fluoro-4-aminochroman-4-carboxylic acid. |
