Water was used as the solvent in the Petasis borono-Mannich reaction. With the use of salicylaldehyde, secondary amines and boronic acids, several alkylaminophenols were obtained in considerably high yields in water. By using the same methodology, 2H-chromenes were prepared with the use of vinyl boronic acids. The reaction mechanism was studied by DFT calculations, and the results obtained corroborate
Petasis 硼-曼尼希反应中使用水作为溶剂。使用水杨醛、仲胺和硼酸,在水中以相当高的收率获得了几种烷基氨基苯酚。通过使用相同的方法,使用乙烯基硼酸制备 2H-色烯。通过DFT计算研究了反应机理,所得结果证实了实验观察到的溶剂效应。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
