摘要

Statistical design of experiments (DOE) was used to rapidly optimize Red-Al reduction of an imide to produce, after deprotection and salt formation, 3, 4-isopropylidenedioxypyrrolidine hydrotosylate (1), an intermediate in the synthesis of Ingliforib. A Red-Al reduction process was successfully scaled to produce multikilogram quantities of 1, thus demonstrating a safer and more economical process. Further development resulted in an optimized procedure, ...
