Description
本発明は、低コレステロール血症剤として有用なヒドロキシアルキル置換アゼチジノンを生成するためのエナンチオ選択的なプロセス、特に、米国特許第5,767,115号で請求された1−(4−フルオロフェニル)−3(R)−[3(S)−ヒドロキシ−3−(4−フルオロフェニル)プロピル)]−4(S)−(4−ヒドロキシフェニル)−2−アゼチジノンを調製するためのエナンチオ選択的なプロセスに関する。
次式により表わされる化合物を調製するプロセスであって:
(a)式IIのp−フルオロベンゾイル酪酸を塩化ピバロイルと反応させ、そして上記生成物を式IIIのキラル補助剤でアシル化して、式IVのケトンを得る工程であって:
(b)キラル触媒の存在下にて、該式IVのケトンを式Vのアルコールに還元する工程;
項目1に記載のプロセスであって、工程(a)において、上記キラル補助剤が、(4S)−4−フェニル−2−オキサゾリジノンであって;工程(b)において、上記キラル触媒が、(R)−テトラヒドロ−1−メチル−3,3−ジフェニル−1H,3H−ピロロ(1,2−c)(1,2,3)オキサザボロリジンであり;工程(c)において、前記シリル保護剤が、クロロトリメチルシランであり、上記ルイス酸が、TiCl4であり、上記4級アミンが、ジイソプロピルエチルアミンであり;工程(d)において、上記シリル化剤が、ビストリメチルシリルアセトアミドであり、上記フッ化物イオン触媒環化剤が、フッ化テトラブチルアンモニウム三水和物である、プロセス。
以下の式によって表される化合物を調製するプロセスであって:
該シリル保護基を除去する工程、を包含する、プロセス。
項目3に記載のプロセスであって、上記シリル保護材が、クロロトリメチルシランであり、上記縮合が、3級アミンの存在下でルイス酸を用いて行われ;そして上記シリル化剤が、ビストリメチルシリルアセトアミドであり、上記フッ化物イオン触媒環化剤が、フッ化テトラブチルアンモニウム三水和物である、プロセス。
