で表わされるα−アルキリデン−1,3−ジオキソラン−2−オン類を製造する。
オートクレーブ中、2−メチル−4−フェニル−3−ブチン−2−オール(801mg,5.0mmol)と、前記式で表わされる触媒1b(45mg,0.25mmol)を導入し、二酸化炭素を圧入(10.0MPa)したのち、100℃で攪拌する。所定の反応時間(15時間)後、反応容器を冷却し、二酸化炭素を放出する。シリカゲルカラムクロマトグラフィーなどの通常の分離操作により、(Z)−5−ベンジリデン−4,4−ジメチル−1,3−ジオキソラン−2−オンが収率75%(768mg,3.76mmol)で得られる。
<実施例2>
オートクレーブ中、2−メチル−3−ブチン−2−オール(426mg,5.0mmol)を、触媒2b(55mg,0.25mmol)の存在下で二酸化炭素の加圧下(4.5MPa)で100℃の温度において攪拌する。所定の反応時間(15時間)後、反応容器を冷却し、二酸化炭素を放出する。蒸留やシリカゲルカラムクロマトグラフィーなどの通常の分離操作により、4,4−ジメチル−5−メチレン−1,3−ジオキソラン−2−オンが収率88%(562mg,4.39mmol)で得られる。
<実施例3>
オートクレーブ中、3−エチル−5−(2−ヒドロキシエチル)−4−メチルチアゾリウム ブロマイド(63mg,0.25mmol)に1,8−ジアザビシクロ[5,4,0]−7−ウンデセン(38mg,0.25mmol)を作用させ系中で触媒5を発生させる。2−メチル−3−ブチン−2−オール(426mg,5.0mmol)を加え、二酸化炭素の加圧下(10.0MPa)で100℃の温度において攪拌する。所定の反応時間(15時間)後、反応容器を冷却し、二酸化炭素を放出する。蒸留やシリカゲルカラムクロマトグラフィーなどの通常の分離操作により、4,4−ジメチル−5−メチレン−1,3−ジオキソラン−2−オン(55mg,0.43mmol)が得られる。
