Young, Steven D. published the artcile< Facile conversion of Hantzsch type 4-aryl-2,6-dimethyl-1,4-dihydropyridine-3,5-carboxylates into 4-aryl-2-methyl-5-oxo-1,4,5,7-tetrahydrofuro[3,4-b]pyridine-3-carboxylates>, Recommanded Product: (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is furopyridinecarboxylate aryl hydro; bromination methylhydropyridinecarboxylate; pyridofuranone aryl; cyclization bromomethylhydropyridinecarboxylate.
Bromination of dihydropyridines I (R = Ph, o-tolyl, 3,4-methylenedioxyphenyl, m-F3CC6H4, C6F5, m-BrC6H4, o-anisyl, o-O2NC6H4; R1 = Me) with pyridinium bromide perbromide gave unstable I (R1 = CH2Br), which, treated with pyridine, cyclized to give 24-63% II.
Synthesis published new progress about Cyclization. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Recommanded Product: (9Z,12Z)-Methyl octadeca-9,12-dienoate.
