Ethyl N-(diphenylmethylene)glycinate Chemical Properties,Usage,Production
Chemical Properties
white to light yellow crystalline powder or
Uses
N-(Diphenylmethylene)glycine Ethyl Ester is used as a reagent in the synthesis of pyrazolopyrrolyl tetrahydropyran DPP-4 inhibitors.
Application
Ethyl N-(diphenylmethylene)glycinate features a diphenylmethylene group that enhances its reactivity and stability, making it particularly useful in organic synthesis and pharmaceutical development.
Reactions
Ethyl N-(diphenylmethylene)glycinate undergoes monoalkylations, dialkylations and Michael additions to ethylenic and acetylenic acceptors under appropriate solid-liquid phase transfer catalysis conditions. Further transformations of the α-disubstituted ketimines lead to α-alkylated aspartic and glutamic acid derivatives.
Synthesis
Ethyl N-(diphenylmethylene)glycinate is prepared by transimination of Benzophenone Imine with alkyl glycinate hydrochloride (room temperature/CH2Cl2).
