A MILD AND CONVENIENT ONE-POT SYNTHESIS OF 4-ARYL-N-OH-HANTZSCH ESTERS
摘要:
A general methodology to prepare a series of 4-Aryl-N-OH Hantzsch esters was developed. The key factor is to control the first-step of Michael addition at 0 degrees C. The method was practical to produce symmetrical and unsymmetric N-OH-Hantzsch esters in moderate yield. This class of compounds might have use in medicinal and material science.
