Abstract
A variety of structurally diverse spirocyclohexane oxindoles featuring a quaternary carbon centre have been successfully constructed through an N‐heterocyclic carbene‐catalyzed [4+2] annulation of isatin‐derived enals with α cyano‐β‐methylenones. This domino process exhibits a wide substrate tolerance, operates under mild conditions, and yields products with high enantioselectivity.
期刊介绍:
Advanced Synthesis & Catalysis (ASC) is the leading primary journal in organic, organometallic, and applied chemistry.
The high impact of ASC can be attributed to the unique focus of the journal, which publishes exciting new results from academic and industrial labs on efficient, practical, and environmentally friendly organic synthesis. While homogeneous, heterogeneous, organic, and enzyme catalysis are key technologies to achieve green synthesis, significant contributions to the same goal by synthesis design, reaction techniques, flow chemistry, and continuous processing, multiphase catalysis, green solvents, catalyst immobilization, and recycling, separation science, and process development are also featured in ASC. The Aims and Scope can be found in the Notice to Authors or on the first page of the table of contents in every issue.
