Chemistry is an experimental science, Application In Synthesis of (1S,2S)-(-)-1,2-Diphenylethylenediamine, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 29841-69-8, Name is (1S,2S)-(-)-1,2-Diphenylethylenediamine
(Chemical Equation Presented) C2-symmetric chiral bisformamides have been shown to catalyze the asymmetric one-pot, three-component Strecker reaction, which produced the alpha-amino nitriles in excellent yields (up to 99%) with good enantioselectivities (up to 86% ee). Optically pure products could be obtained after a single recrystallization. A possible transition state (TS 1) has been proposed to explain the origin of asymmetric inductivity and reactivity according to the geometry of catalyst 2a optimized at the B3LYP/6-31G(d) level and the absolute configuration of product 4a.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Application In Synthesis of (1S,2S)-(-)-1,2-Diphenylethylenediamine, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 29841-69-8, in my other articles.
