摘要:
The organocatalytic enantioselective decarboxylative addition of malonic acids half thioesters to isatins using a squaramide catalyst afforded the products with high enantioselectivity. These products are key intermediates in the synthesis of 3-substituted 3-hydroxy-2-oxindole derivatives. The first enantioselective synthesis of (-)-flustraminol B has been accomplished.
