Synthesis of (2-Oxoindolin-3-ylidene)methyl Acetates Involving a C−H Functionalization Process
摘要:
[GRAPHICS]A novel palladium-catalyzed oxidative C-H functionalization protocol for the synthesis of (2-oxoindolin-3-ylidene)methyl acetates has been developed. In the presence of Pd(OAC)(2) and Phl(OAC)(2), a variety of N-arylpropiolamides underwent the C-H functionalization reaction with acids to afford the corresponding (E)-(2-oxoindolin-3-ylidene)methyl acetates selectively in moderate to excellent yields.
AgSCF<sub>3</sub>-Mediated Oxidative Trifluoromethythiolation of Alkynes with Dearomatization to Synthesize SCF<sub>3</sub>-Substituted Spiro[4,5]trienones
A new method for the AgSCF3-mediated radical cascade difunctionalizing trifluoromethythiolation of alkynes with dearomatization is developed. This protocol provides a novel route to SCF3-substituted spirocyclic compounds via the formation of one C-SCF3 bond, one C-C bond, and one C-O double bond in a single step.
