Abstract

A successful rapid synthesis of dendritic benzyl chlorides from dendritic benzyl alcohols using methanesulfonyl chloride/$Et_3N$ as activating agents was described. In this method, each dendritic benzyl chloride can be prepared in one pot: no isolation of intermediate mesylated dendrons is required. The key steps in the syntheses of dendritic benzyl chlorides were the mesylation of the hydroxymethyl group followed by the chlorination by in-situ generated triethylammonium chloride.

덴드리틱 벤질 알코올을 트리에틸아민과 메탄술포닐클로라이드와 반응시켜서, 덴드리틱 벤질 클로라이드의 효율적인 합성이 이루어졌다. 이 반응은 히드록시기의 메실화 반응과 염소화 반응의 2단계 반응으로 이루어지는데, 중간체의 분리없이 한 반응 용기내에서 반응이 진행되는 경제적인 방법이다.
