- W2949204557 abstract "The novel tricyclic sila-heterocycles rac-2,8-diethoxy-6,6-diorganyl-3,9-diaza-6-silatricyclo[5.2.1.04,8]dec-2-enes rac-4a (organyl = Me) and rac-4b (organyl = Ph) were synthesized in two-step, one-pot syntheses, starting from 3,6-diethoxy-2,5-dihydropyrazine (1). Metalation of 1 with 1 molar equiv of n-BuLi and subsequent treatment with 1 molar equiv of the (chloromethyl)silanes R2Si(CHCH2)CH2Cl (R = Me, Ph) yielded the respective 2-R2Si(CHCH2)CH2-substituted 3,6-diethoxy-2,5-dihydropyrazines rac-3a (R = Me) and rac-3b (R = Ph). Treatment of rac-3a and rac-3b with 1 molar equiv of n-BuLi, followed by hydrolysis, finally yielded rac-4a and rac-4b, respectively. Compounds rac-4a and rac-4b were structurally characterized by multinuclear NMR studies and crystal structure analyses. In addition, some mechanistic aspects of the cyclization reactions rac-3a → rac-4a and rac-3b → rac-4b were investigated." @default.
