Reactivity of 2-cyano-1,4,5,6-tetrahydro-1-pyridinecarboxylic acid esters towards various nucleophiles: Regio- and stereoselectivity of the attack
摘要:
The synthesis and reactivity of the title compounds towards nucleophiles are discussed. The regio-and diastereoselectivity of the attack is highly dependent on the carbamic ester and the type of nucleophile applied. Both Michael type addition across the activated double bond and S(N)2T reaction at the carbamate carbon atom were observed. Structure assignment of the adducts in solution and in the solid state was performed utilizing high temperature NMR techniques as well as single crystal X-ray diffraction.

The first organocatalyticenantioselectiveCHalkenylation and arylation reactions of N‐carbamoyl tetrahydropyridines and tetrahydro‐β‐carbolines (THCs) are described. The metal‐free processes represent an efficient and straightforward approach to a variety of structurally and electronically diverse α‐substituted tetrahydropyridines and THCs in good yields with excellent regio‐ and enantioselectivities
