Mixing readily available alkynes, pyrroles, and triethylsilane along with an indium catalyst was found to be an efficient procedure to introduce alkyl groups onto a β-position of pyrroles in a complete regioselective manner. This is the first demonstration of catalytic β-alkylation of pyrroles in a single step.
已发现将易于获得的炔烃,吡咯和三乙基硅烷与铟催化剂混合是一种以完全的区域选择性方式将烷基引入吡咯的β-位的有效方法。这是一步法证明吡咯的β-烷基催化反应。
