Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Organic Letters called Modular Synthesis of Highly Substituted Pyridines via Enolate α-Alkenylation, Author is Hardegger, Leo A.; Habegger, Jacqueline; Donohoe, Timothy J., which mentions a compound: 3194-15-8, SMILESS is O=C(C1=CC=CO1)CC, Molecular C7H8O2, SDS of cas: 3194-15-8.
A novel methodol. for the synthesis of highly substituted pyridines e. g., I, based on the palladium-catalyzed enolate α-alkenylation of ketones is presented; the formation of aromatic compounds is a new direction for this catalytic C-C bond forming reaction. In the key step, a protected β-haloalkenylaldehyde participates in α-alkenylation with a ketone to afford a 1,5-dicarbonyl surrogate, which then undergoes cyclization/double elimination to the corresponding pyridine product, all in one pot. The β-haloalkenylaldehyde starting materials can be obtained from the corresponding methylene ketone via Vilsmeier haloformylation. Using this concise route, a variety of highly substituted pyridines were synthesized in three steps from com. available compounds
