Novel compounds of Formula (I) or pharmaceutically acceptable salts thereof, metabolites thereof, isomers thereof, enantiomers thereof or prodrugs thereof of Formula (I)
wherein the substituents are as defined herein, which are useful as therapeutic agents.
The Rh(III)-catalyzed C8-allylation of quinoline N-oxides has been accomplished using vinylcyclopropanes as an allyl source with excellent diastereoselectivity at room temperature. The C–H/C–Cactivation, substrate scope and natural product mutation are the important practical features.
Rh( III ) 催化的喹啉N-氧化物的 C8-烯丙基化已使用乙烯基环丙烷作为烯丙基源,在室温下具有出色的非对映选择性。C - H/C - C激活、底物范围和天然产物突变是重要的实用特征。
Site-Selective C8-Alkylation of Quinolines with Cyclopropanols: Merging C–H/C–C Bond Activation
The site-selective C8-alkylation of quinolines has been accomplished using cyclopropyl alcohols as the alkylating agents and N-oxide as a weak chelating group in the presence of Co(III) catalysis via merging C–H/C–C bond activation. The use of cyclopropanol as the alkyl source, Co catalysis, substrate scope, HRMS analysis of the reaction intermediate, and late-stage mutation of drug molecules/natural
