reaction can also be performed efficiently as a three-component assembly of alkynes, pyrroles, and carbon nucleophiles in one batch. The strategy is highly useful to synthesize methanes having four different carbon substituents. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
发现在铟催化剂的存在下,与勐二吡咯烷烃中的 sp3 碳原子结合的吡咯基被一定范围的碳亲核试剂成功取代。该反应也可以作为一批炔烃、吡咯和碳亲核试剂的三组分组装有效地进行。该策略对于合成具有四个不同碳取代基的甲烷非常有用。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
