[Display omitted] • A Ru-catalysed universal transfer hydrogenation, deuteration, and methylation of diverse functional compounds using MeOH. • General and convenient TH/TD strategy to large-scale synthesize of deuterated pharmaceuticals. • Kinetic and mechanistic investigations of Ru-catalyzed TH/TD protocols. Catalytic valorization of methanol in organic synthesis and energy technologies is interesting and important for both fundamental research and industrial applications. In particular, its utilization as hydrogen, deuterium and methyl sources for selective reduction and deuteration reactions as well as to access N -methylated products is highly desirable and can be considered as a potential methodology for the amplification of transfer hydrogenation and C1 chemistry. Here, we report homogeneous Ru-MACHO complex catalyzed transfer hydrogenation of different functionalized compounds such as ketones, aldehydes, alkynes, alkenes, imines, azobenzenes, and nitro compounds as well as deoxygenation of N -oxide derivatives employing methanol as an affordable hydrogen donor and solvent. This Ru-based strategy has been proven to be very convenient for the deuteration process to synthesize advanced deuterium-labelled compounds, including the gram-scale synthesis of deuterated pharmaceuticals such as d -Cloperastine, d -Buclizine, d -Diphendyarmine, d -Modafinil, and d -Adrafinil using CD 3 OD. In addition, the application of methanol as a C1 source for the preparation of N -methylated products is showcased. Finally, kinetic and mechanistic investigations for this Ru-catalyzed transfer hydrogenation and deuteration protocols have been performed. [ABSTRACT FROM AUTHOR] |
