Regioselective synthesis of 1-alkyl-5-(indol-3-yl- and -2-yl)pyrrolidin-2-ones from available reagents
摘要:
The reaction under mild conditions of 1-alkyl-5-hydroxypyrrolidin-2-ones with different indoles having a free 3 position leads exclusively to 1-alkyl-5-(indol-3-yl)pyrrolidin-2-ones but if position 3 is occupied to 1-alkyl-5-(indol-2-yl)pyrrolidin-2-ones.

Primary aliphaticcarboxylicacids were treated with N-iodosuccinimide (NIS) in 1,2-dichloroethane to form the corresponding alkyl iodides under warming conditions. Based on these results, those aliphaticcarboxylicacids were treated with NIS, followed by the reaction with K2CO3 to give the corresponding N-alkylsuccinimides in good yields in one pot. Moreover, those aliphaticcarboxylicacids were treated
