Quality Control of Ethyl indoline-2-carboxylate. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: Ethyl indoline-2-carboxylate, is researched, Molecular C11H13NO2, CAS is 50501-07-0, about Regiospecific functionalization of indole-2-carboxylates and diastereoselective preparation of the corresponding indolines. Author is Collot, Valerie; Schmitt, Martine; Marwah, Padma; Bourguignon, Jean-Jacques.
The N-acyl derivatives of 3-substituted indole-2-carboxylates prepared through several routes were submitted to catalytic hydrogenation affording either cis- or trans-indoline diastereomers after quant. C-2 epimerization.
