OPTICALLY ACTIVE NITRO ALCOHOL DERIVATIVES, OPTICALLY ACTIVE AMINO ALCOHOL DERIVATIVES, AND PROCESS FOR PREPARING THE SAME

摘要

Optically active 1-substituted phenyl-2-nitro alcohol derivatives having the formula (1) and the process for producing thereof, and 1-substituted phenyl-2-amino alcohol derivatives having the formula (2) and the process for producing thereof from the optically active 1-substituted phenyl-2-nitro alcohol derivatives. From these nitro alcohols, pharmaceuticals such as (R)-albutamin and (R)-sarmeterol useful as a bronchodilator is obtained via optically active amino alcohols which are useful pharmaceutical intermediates.
