영문초록

2-Amino-와 2-nitro-3,4-dihydro-5,6-dimethoxy-1(2H)-naphthalenone의 촉매수소화에서 주생성물인 2-amino-5,6-dimethoxy-1,2,3,4-tetrahydronaphthalene을 얻었고 동시에 극소량의 5,6-dimethoxy-1,2,3,4-tetrahydro-2(1H)-naphthalenone을 얻었다. 이 전이된 생성물의 구조결정은 ir와 nmr, 그리고 원소분석으로 확인하였고 전이메카니즘을 제시하였다

기타언어초록

From the catalytic reductions of the respective 2-amino-, and 2-nitro-3,4-dihydro-5,6-dimethoxy-1(2H)-naphthalenone, a major reduction product of 2-amino-5,6-dimethoxy-1,2,3,4-tetrahydro-naphthalene was obtained, along with a minute amount of rearranged product, 5,6-dimethoxy-1,2,3,4-tetrahydro-2(1H)-naphthalenone. The unusual formation of 5,6-dimethoxy-1,2,3,4-tetrahydro-2(1H)-naphthalenone was verified on the basis of ir, and nmr spectra, and elemental analysis. A plausible mechanism for the rearrangement is proposed
