Studies on the Safrole Derivatives. Part V

open access: yesJournal of the agricultural chemical society of Japan, 1959
(1) サフロールおよびジヒドロサフロールとアセトアルデヒドとの反応において,氷酢酸溶媒中濃硫酸を縮な合剤としてBeayer反応を行い, Baeyer反応生成物であるジフェニルエタン誘導体を得た.また新たにサフロールのBlanc-Quelet反応を行い,反応生成物である6-クロルエチル誘導体からα-アセトキシエチルベンゼン,α-ヒドロキシエチルベンゼン誘導体などを合成した. (2) イソサフロールとアセトアルデヒドの反応において,溶媒として氷酢酸のかわりにベンゼンを,縮合剤に塩酸を用い室温で反応させたところ,イソサフロールのPrins反応生成物4-(3', 4'-メチレンジオキシフェニル)-2, 5, 6-トリメチル-1, 3-ジオキサンを84%収率でしかも簡易に得る方法を見出した.
