On April 19, 2013, Senczyszyn, Jemma; Brice, Heloise; Clayden, Jonathan published an article.Formula: C11H19ClO2 The title of the article was Spirocyclic Dihydropyridines by Electrophile-Induced Dearomatizing Cyclization of N-Alkenyl Pyridinecarboxamides. And the article contained the following:
On treatment with acylating or sulfonylating agents, N-alkenyl pyridinecarboxamides (N-pyridinecarbonyl enamines) undergo a dearomatizing cyclization initiated by pyridine acylation and followed by intramol. trapping of the resulting pyridinium cation (e.g., I → II). The products are spirocyclic dihydropyridines which may be further elaborated to spirocyclic heterocycles with drug-like features. The experimental process involved the reaction of (1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl carbonochloridate(cas: 14602-86-9).Formula: C11H19ClO2
The Article related to electrophile induced dearomatizing spirocyclization alkenylpyridinecarboxamide, spirocyclic hydropyridine preparation, Heterocyclic Compounds (One Hetero Atom): Spiro Compounds With One Hetero Atom In Each Ring and other aspects.Formula: C11H19ClO2
