Electric Literature of C4H7BrO2. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: 2-Bromomethyl-1,3-dioxolane, is researched, Molecular C4H7BrO2, CAS is 4360-63-8, about Unexpected Formation of Thiophene in the Pyrrole Synthesis from Methoxyallene and Methyl Isothiocyanate. Author is Tarasova, O. A.; Nedolya, N. A.; Albanov, A. I.; Trofimov, B. A..
The sequential reaction of lithiated methoxyallene, Me isothiocyanate, and 2-(bromomethyl)-1,3-dioxolane in the presence of CuBr yields a 2,3-disubstituted thiophene instead of the expected pyrrole. The process was accomplished in one preparative stage and involved intramol. cyclization of the in situ-generated lithium allenylimidothioate and N-alkylation of the resulting lithium thienylamide. Varying the reaction conditions did not affect its route: in all cases, the only product was N-(1,3-dioxolan-2-ylmethyl)-3-methoxy-N-methylthiophen-2-amine.
