초록

4-Methyl-2,6,7-trioxa-1-phospbicycle[2,2,2]octane 1-sulfide (BPS)와 4-Methyl-2,6,7-trioxa-1-phosphabicyclo[2,2,2]octance 1-oxide (BPO) 및 관련 단고리화합물을 합성하였고 반응성 중간체와 반응기작을 알아보기 위하여 BPS를 chloroform 및 methanol중에서 MCPBA로 산화시켰다. Chloroform에서는 BPO만이 생성되었고 methanol중에서는 두고리 구조가 열려서 만들어진 반응성 중간체가 methanol을 인산화하여 생성된 이성질체의 단고리화합물이 관찰 되었으며 또한 소량의 BPO도 생성되었다. 인산화 능력을 소유한 반응성 중간체를 여러 가지 기기분석을 동원하여 연구한 결과 그 구조는 단고리 methyl sulfenyl ester로 제안하였다.

Abstract

4-Methyl-2,6,7-trioxa-1-phosphabicyclo [2,2,2] octane 1-sulfide (BPS), 4-Methyl-2,6,7-trioxa-1-phosphabicyclo[2,2,2] octane 1-oxide (BPO) and related monocyclic methylphosphates were prepared and the oxidation of BPS with MCPBA in chlorofrom or methanol was carried out to investigate the formation of reactive intermediates and reaction mechanism. BPO was the only product in chloroform while in methanol isomeric monocyclic methylphosphates were formed through opening of bicylic structure with subsequent phosphorylation of methanol by reactive intermediate formed in reaction. Formation of little amount of BPO was also observed. The structure of phosphorylating intermediate was probed with various spectroscopic methods and monocyclic methyl sulfenyl ester was suggested as a possible structure.
