WebNew 1′-homocarbanucleoside analogs with an optically active substituted bicyclo[2.2.1]heptane skeleton as sugar moiety were synthesized. The pyrimidine analogs with uracil, 5-fluorouracil, thymine and cytosine and key intermediate with 6-chloropurine (5) as nucleobases were synthesized by a selective Mitsunobu reaction on the primary … WebSOLUTION: The optically active 2-amino-2-phenylethanol compound represented by general formula (3) (wherein R 1 is a lower alkoxyl group or the like; and * is an asymmetrical carbon atom) is obtained by reacting in a solvent a 2-amino-2-phenylethanol compound represented by general formula (1) (wherein R 1 is the same as above) with an ...
