β-Difluoro-α-trimethylsilyl-γ-lactam 유도체의 합성
채규윤,곽경철,문재정,최장호 圓光大學校 基礎自然科學硏究所 2000 基礎科學硏究誌 Vol.18 No.1
α-위치만 선택적으로 difluoromethylene기가 도입된 α.α-difluoro-γ-trimethylsilyl-γ-lactam 유도체(6)들은 ethyl α.α-difluoro-γ-trimethylsilyl-γ-iodopentanoate(4)는 일차아민 유도체와의 반응으로부터 비교적 편리한 작용조건과 비교적 좋은 수득률로 합성하였다. The target of α.α-difluoro-γ-trimethylsilyl-γ-lactam derivatives(6) with selectively in corporated difluoromethylene on α-position were readily prepared form reaction ethyl α.α-difluoro-γ-trimethylsilyl-γ-iodopentanoate(4) and primary derivatives in moderate yields.
Diethyl 3,4,5, - Trimethoxybenzylmalonate의 새로운 합성법
李茶浩,李英行,李晩求,蔡奎允 圓光大學校 1984 論文集 Vol.18 No.2
3,4,5 - Trimethoxybenjoyl chloride 와 diethyl malonate를 축합시키고 이어서 염소화반응 및 수소화반응에 의하여 70%의 수득률로서 diethyl 3,4,5 - trimethoxybenzylmalonate를 얻었다. direct condensation of 3,4,5 - trimethoxybenzoyl chloried with diethyl malonate followed by chlorination and hydrogenation afforded diethyl 3,4,5 - trimethoxybenzylmalonate in 70% overall yield.
