Abstract

The cycloaddition between homophthalic anhydrides (1 or 2) and diethyl azodicarboxylate and ethyl arylmetbyldenecarbamates was investigated. The former led to 2,3-diethoxycarbonyl-2,3-dihydro-1-hydroxyphthalazines (3 and 4), while the latter gave 3-aryl-4-carboxy-2-ethoxycarbonyl-3,4-dihydro-1(2H) isoquinolinones (5∼10).

호모프탈산 무수물(1또는 2)과 디에틸 아조디카르복시산 및 에틸 아릴메티리덴카르밤산과의 고리화첨가반응을 검토하였다. 전자의 반응에서는 2,3--디에톡시카르보닐-2,3-디히드로-1-히드록시프탈라진들(3 및 4)이 생성되었으며, 후자의 반응에서는 3-아릴-4카르복시-2-에톡시카르보닐-3,4-디히드로-1(2H)-이소퀴놀린온들(5~10)이 생성되었다.
