An efficient, facile and environmentally benign synthesis of a library of 1,2,3-triazolyl chalcone hybrids (3a–u) has been accomplished by grinding the reactants at room temperature in excellent yields in very short reaction time. Subsequently, SbCl3 catalysed Michael addition of indoles to the chalcones afford 1,2,3-triazolyl indole hybrids (5a–l) in excellent yields.
通过在室温下研磨反应物,我们在极短的反应时间内高效、简便、环保地合成了 1,2,3-三唑基查尔酮杂化物(3a-u)。随后,在 SbCl3 催化下,吲哚与查耳酮的迈克尔加成反应以极好的收率得到了 1,2,3-三唑基吲哚杂环(5a-l)。
