The one-step polyfunctionalization of 2- and 3-(methylthio)thiophenes was investigated. Direct polymetalation with superbases followed by quenching with an appropriate electrophile led to 2,αS-disubstituted derivatives starting from 2-(methylthio)thiophene, and 2,5,αS-trisubstituted derivatives starting from 3-(methylthio)thiophene.
研究了2-和3-(甲硫基)噻吩的一步多官能化。用超碱直接多金属化,然后用合适的亲电试剂淬灭,得到从 2-(甲硫基)噻吩开始的 2,αS-二取代衍生物和从 3-(甲硫基)噻吩开始的 2,5,αS-三取代衍生物。
