2,3-Dihydropyrrolo[1,2-b]benzisothiazole 5,5-Dioxide들의 비대칭성 광이성질화 반응 A New Asymmetric Photoisomerization of 2,3-Dihydropyrrolo[1,2-b]benzisothiazole 5,5-Dioxides원문보기
245 nm mercury lamp를 사용하여 2,3-dihydropyrrolo[1,2-b]benzisothiazole 5,5-dioxide를 광이성질화 반응시켜서 2,3-dihydro[1]benzothieno[3,2-b]pyrrole 4,4-dioxide를 가지고 있는 tricyclic ring system 화합물을 합성하는 방법을 개발하였다. 합성한 화합물들에 대한 구조는 IR, NMR, MS 및 single crystal X-ray crystallography를 이용하여 결정하였다.
