In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Efficient Synthesis of a Trisubstituted 1,6-Naphthyridone from Acetonedicarboxylate and Regioselective Suzuki Arylation, published in 2005-12-09, which mentions a compound: 1001-26-9, Name is Ethyl 3-Ethoxy-2-Propenoate, Molecular C7H12O3, Related Products of 1001-26-9.
An efficient five-step synthesis of 1,6-naphthyridone I, a p38 mitogen-activated protein (MAP) kinase inhibitor intermediate, in 32% overall yield starting from acetonedicarboxylate (ADC) is described. The synthesis began with a selective monoamidation of ADC di-Me ester enolate. A novel concomitant enamine formation and an imide cyclization afforded the nitrogen differentially protected enamide imide. Treatment of this with KOCMe3 and 3-ethoxyacrylate produced lactam quant., which was converted to tetrachloronaphthyridone via a one-pot p-methoxybenzyl deprotection and bischlorination. A highly regioselective Pd(OAc)2/IMes-catalyzed Suzuki coupling completed the synthesis.
