According to the need of synthesis, the simplicity of operation as well as the yield , we pick and choose the reaction conditions. the final choice is the optimal synthetic route that 8benzyl2,8diazaspiro[]decan3one with antibacterial activity was synthesized from 1benzylpiperidin4one. The structures of all the final pounds and the important intermediate pounds have been confirmed by 1HNMR and LCMS analysis. Keywords: spiropound。 Olefination。 antibacterial III 符號說明 g, 克 ; h, 小時 ; min, 分鐘; mL, 毫升; mol, 摩爾; ℃ , 攝氏度; ., Room Temper, 室溫; δ, 化學位移 , 單位 ppm; , Analytical Reagent,分析純; Ar, Aryl,芳基; Ph, Phenyl,苯基; TBAF, Tetrabutylammonium fluoride,四丁基氟化銨; EtOH, Ethano
