WebDec 31, 2012 · The direct nucleophilic addition of alkyl amines to the α(δ')-carbon atom of dimethyl (E)-hex-2-en-4-ynedioate to generate α,β-dehydroamino acid derivatives is reported. Herein, we have studied the reactivity of various primary and secondary alkyl amines in the α-selective nucleophilic conjugate addition to conjugated dimethyl (E)-hex-2-en-4 … WebStructure: The amine functional group consists of an N atom bonded either to C or H atoms via σ bonds.; Both the C-N and the N-H bonds are polar due to the electronegativity of the N atom.; The trigonal pyramidal arrangement of bonds around nitrogen is shallower in aryl amines vs alkyl amines.; This is a result of resonance delocalisation of the lone pair into …
