On November 4, 2016, Lansakara, Ashabha I.; Mariappan, S. V. Santhana; Pigge, F. Christopher published an article.Synthetic Route of 929-37-3 The title of the article was Alkylidene Dihydropyridines As Synthetic Intermediates: Model Studies toward the Synthesis of the Bis(piperidine) Alkaloid Xestoproxamine C. And the article contained the following:
Results of model studies demonstrating a stereoselective synthetic route to tricyclic analogs of the bis(piperidine) alkaloid xestoproxamine C are presented. Dearomatization of a tricyclic pyridine derivative to afford an alkylidene dihydropyridine (anhydrobase) intermediate followed by catalytic heterogeneous hydrogenation was used to install the correct relative stereochem. about the bis(piperidine) ring system. Other key features of these model studies include development of an efficient ring-closing metathesis procedure to prepare macrocyclic derivatives of 3,4-disubstituted pyridines, intramol. cyclizations of alkylidene dihydropyridines to establish pyridine-substituted pyrrolidines and piperidines, successful homologation of pyridine-4-carboxaldehydes using formaldehyde di-Me thioacetal monoxide (FAMSO), and application of B-alkyl Suzuki coupling to assemble substituted pyridines. The experimental process involved the reaction of 2-(2-(Vinyloxy)ethoxy)ethanol(cas: 929-37-3).Synthetic Route of 929-37-3
