Metal-Free Oxidative Spirocyclization of Hydroxymethylacrylamide with 1,3-Dicarbonyl Compounds: A New Route to Spirooxindoles
摘要:
A metal-free oxidative spirocyclization of hydroxymethylacrylamide with 1,3-dicarbonyl compounds is described. The reaction proceeds through tandem dual C-H functionalization and intramolecular dehydration, in which two new C-C bonds and one C-O bond were formed. This method affords a novel and straightforward access to various spirooxindoles under mild conditions.
Cascade synthesis of spirooxindole δ-lactone derivatives through N-aryl hydroxymethylacrylamides with xanthates
摘要:
A novel and highly efficient cascade synthesis of spirooxindole delta-lactone derivatives from N-aryl hydroxymethylacrylamides and xanthates in good yields is described. The reaction proceeds through a radical addition/cyclization and ester exchange, in which two new C-C bonds and one C-O bond were formed. (C) 2015 Elsevier Ltd. All rights reserved.
