A practical large-scale synthesis of monomethyl malonate and monoethyl malonate, which are among the most commonly applied half-esters in organic synthesis, is described, applying the highly efficient selective monohydrolysis of symmetric diesters we reported before. The optimal conditions with regard to the type of base, equivalent, co-solvents, and the reaction time have been examined for large-scale reactions. Monomethyl malonate and monoethyl malonate were obtained in high yields with near… 
Practical Large Scale Synthesis of Half-Esters of Malonic Acid
and monoethyl malonate are very important building blocks. They have been frequently applied to synthesis of a variety of significant pharmaceuticals and natural products. However, their commercial
Synthesis of Dissymmetric Malonic Acid Monoamides from Symmetric Dithiomalonates
We report a highly selective synthesis of dissymmetric S,N-malonates from symmetric dithiomalonates under mild conditions. This reaction was accelerated using a Cu(II) catalyst developed by us. When
Hydrolysis of esters and dialkyl malonates mediated by t-BuNH2/LiBr/alcohol/H2O
An efficient, simple protocol for the ester hydrolysis and monohydrolysis of dialkyl malonates by t-BuNH2/MeOH/H2O with or without LiBr is described. The method is of general applicability since
Non-Enzymatic Desymmetrization Reactions in Aqueous Media
TLDR
This review focuses on the recent progress of desymmetrization reactions of symmetric organic compounds in aqueous media without utilizing enzymes.
Metal Catalyzed Synthetic Reactions via Aerobic Oxidation as a Key Step
TLDR
The aerobic Rh/C-catalyzed oxidative homo- and cross-coupling of aryl amines was developed and provided a mild, operationally simple, and efficient approach for the synthesis of biaryls which are important to pharmaceutical and materials chemistry.
Optimization of the Selective Monohydrolysis of Diethyl 4-Aryl-4H-pyran-3,5-dicarboxylates
TLDR
The utility of this process is demonstrated by the monohydrolysis of a series of 4-aryl-4H-pyran-3,5-dicarboxylate esters to afford the corresponding monoesters in 20–80% yields under the optimized conditions.
Remote exo/endo selectivity in selective monohydrolysis of dialkyl bicyclo[2.2.1]heptane-2,3-dicarboxylate derivatives.
High exo-facial selectivity was observed in the selective monohydrolysis of a series of near-symmetric diesters that possess an exo-ester group and an endo-ester group attached on a norbornane or
