Bis(alkylthio)carbenes as Novel Reagents for Organic Synthesis
摘要:
Bis(alkylthio)carbenes have been shown to be a useful class of reactive intermediates for applications to organic synthesis. Substituted hydroindolanes, isatins and hydroquinolones can be prepared by the addition of these carbenes to vinyl isocyanates. (C) 2000 Elsevier Science Ltd. All rights reserved.
