Reported herein is an enantiodivergent synthesis of chiral biaryls by a chiral phosphoric acid catalyzed asymmetric transfer hydrogenation reaction. Upon treatment of biaryl lactols with aromatic amines and a Hantzsch ester in the presence of chir...
Oxidative C(sp(3))-H bond functionalization of the 1-position of tetrahydroisoquinoline (THIQ) derivatives was performed by using diethyl azodicarboxylate (DEAD) as the oxidant. A wide range of nucleophiles, including ketene silyl acetal, silyl en...
A one-pot tandem approach for the synthesis of benzothiazoles from benzyl halides and o-aminobenzenethiol was described. Benzothiazoles were obtained in high chemical yields under mild conditions in DMSO in the absence of an additional oxidant. Bo...

Described herein is a chiral magnesium bisphosphate-catalyzed asymmetric double C(sp3)-H bond functionalization triggered by a sequential hydride shift/cyclization process. This reaction consists of stereoselective domino C(sp3)-H bond functionali...
The Tishchenko reaction is one of the useful methods for ester synthesis. Intra- and intermolecular Tishchenko reactions using metallic zinc are described. A practical Tishchenko reaction using metallic zinc was applied to various benzaldehydes to...
