A new class of thioamide-substituted cinchona derivatives is reported. A convergent and practical approach was developed to insert the thioamide functional group onto the cinchonidine from readily available dithioesters. These organocatalysts were ef

A rapid and convenient method has been developed for the stereoselective synthesis of alpha,beta-diamino acid derivatives from amido-substituted Malonic Acid Half Oxyesters (MAHOs) and imines. The anti-products were obtained with a diastereomeric rat

An efficient and direct approach was developed for the synthesis of α,β-dehydroamino acid derivatives with a broad range of substrates. Amido-substituted Malonic Acid Half Oxyesters (MAHOs) have proven to be excellent partners of various aromatic a

A novel synthetic route for arylated 1,4-benzothiazine derivatives has been developed. This method utilizes a key intramolecular nucleophilic aromatic substitution step of the corresponding (Z)-β-(2-fluorobenzenesulfonyl)vinylamine intermediate to c
