Chemo-Enzymatic One-Pot Two-Step Functionalization of 1,2,3,4-Tetrahydroisoquinolines by Monoamine Oxidase-Ugi-Joullié Reaction Sequence

A one-pot two-step chemo-enzymatic approach for the functionalization of substituted 1,2,3,4-tetrahydroisoquinolines (THIQs) was developed. The system combines monoamine oxidase (MAO)-catalyzed imine formation with Ugi-type three-component reaction in an aqueous buffer without intermediate isolation. The two steps were separately optimized for buffer and pH to obtain the expected products. MAOs enabled the functionalization of fifteen THIQs by oxidation to imines, while the Ugi-Joullié-reaction was successfully carried out with eight carboxylic acids and eight isonitriles. 41 products were isolated giving access to valuable building blocks for medicinal chemistry applications. Gram-scale transformation demonstrated the utility of the described protocol for organic synthesis.

Integrating Hydrogen Production with Aqueous Selective Semi-Dehydrogenation of Tetrahydroisoquinolines over a Ni2P Bifunctional Electrode

Exploring an alternative anodic reaction to produce value-added chemicals with high selectivity, especially integrated with promoted hydrogen generation, is desirable. Herein, a selective semi-dehydrogenation of tetrahydroisoquinolines (THIQs) is demonstrated to replace the oxygen evolution reaction (OER) for boosting H2 evolution reaction (HER) in water over a Ni2P nanosheet electrode. The value-added semi-dehydrogenation products, dihydroisoquinolines (DHIQs), can be selectively obtained with high yields at the anode. The controllable semi-dehydrogenation is attributed to the in situ formed NiII/NiIII redox active species. Such a strategy can deliver a variety of DHIQs bearing electron-withdrawing/donating groups in good yields and excellent selectivities, and can be applied to gram-scale synthesis. A two-electrode Ni2P bifunctional electrolyzer can produce both H2 and DHIQs with robust stability and high Faradaic efficiencies at a much lower cell voltage than that of overall water splitting.

Development of a scalable synthesis of a VEGFR inhibitor

Process development and salt selection for a novel VEGFR inhibitor are described. The overall convergent synthesis involved coupling of three key fragments, 2-chloronicotinoyl chloride, 4-isopropyl-3-methylaniline and 7-aminoisoquinoline. A cost-effective
