A rhodium-catalyzed sequential oxidative C-H annulation reaction between ketazines and internal alkynes has been developed via C-H and N-N bond activation with air as an external oxidant, which led to an efficient approach toward isoquinolines with high atom efficiency at rt. Utilizing the distinctive reactivity of this catalysis, both N-atoms of the azines could be efficiently incorporated to the desired isoquinolines under very robust and mild reaction conditions.

A novel bacterium capable of producing allitol from D-psicose was isolated from soil and identified as Klebsiella oxytoca G4A4. An efficient method for the transformation of D-psicose to allitol was achieved through the resting cell reaction. Ribitol as an inducer is suitable for cell cultivation, and cells are most active in Tris-HCl buffer (pH 8.0) at 37 °C with a density of 40 (OD600 nm ). After the reaction, the final conversion rates of the washed cells were approximately 87, 83, and 55% at D-psicose concentrations of 0.25, 0.5, and 1%, respectively. The product from D-psicose was purified and determined to be allitol by high-performance liquid chromatography and nuclear magnetic resonance spectroscopy.
