Improvement of a Critical Intermediate Step in the Synthesis of a Nitroxide-Based Spin-Labeled Deoxythymidine Analog

摘要

Methods to reduce the carboxylic acid moiety in 3-carboxy-2,2,5,5-tetramethylpyrrolin-1-oxyl to an alcohol as an intermediate toward the corresponding aldehyde have been explored and an improved method has been developed.
