Efficient macrocyclization can be conducted at high concentrations employing microwave irradiation and a phase separation strategy. The rate of the GlaserâHay macrocyclization is accelerated using microwave irradiation and reaction times decreased from 48 h to 1â6 h, depending on the nature of the substrate. Macrocyclization concentrations could be increased up to 0.1 M compared to traditional concentrations (0.2 mM).
可以利用微波照射和相分离策略,在高浓度下进行有效的环化反应。通过微波照射,Glaser-Hay环化反应的速率加快,反应时间从48小时缩短到1至6小时,具体取决于底物的性质。与传统浓度(0.2 mM)相比,环化反应的浓度可以提高到0.1 M。
