A facile, green, one-pot oxidation of primary alcohols to carboxylic acids with broad substrate applicability has been developed by employing an expedient catalytic system consisting of 1-Me-AZADO⁺X⁻/NaClO₂ .

A versatile, highly enantiocontrolled entry to the spiro-β-lactam core of chartellines has been developed by expanding the scope of oxidative nitrogen atom transfer methodology based on chiral Rh-nitrenoid species.

Herein, we describe the first asymmetric total synthesis of (–)-martinelline ((–)-2) and the second total synthesis of (–)-martinellic acid ((–)-1) by employing a tandem Mukaiyama–Mannich reaction/aminal cyclization as the key step.
