Abstract

本發明係關於一種相關於4-胺基茚滿衍生物轉換不需要之S鏡相異構物形式為其有用之外消旋體的新穎方法。

Description

轉換S-鏡相異構物為其外消旋形式之方法
本發明係關於化合物7-氟-1,1,3-三甲基-2,3-二氫-1H-茚-4-胺(「化合物II」),其係適用於製備殺真菌化合物3-二氟甲基-N-(7-氟-1,1,3-三甲基-4-茚滿基)-1-甲基-4-吡唑甲醯胺(「化合物I」)之中間產物。更特定言之,本發明係關於化合物II之S鏡相異構物及其製備。化合物I及II之式如下:
化合物I係最近發現之殺真菌分子。Venturini,Isabella等人之專利申請案WO2012084812首先描述了作為農業用途之殺真菌劑之化合物I及其合成。在結構上,化合物I係醯胺化合物且因此可容易地藉由用於製備彼等醯胺化合物之常規製程獲得。舉例而言,化合物I可藉由使化合物II與提供所得化合物I之相對應茚滿部分之相對應吡唑羧酸或吡唑羧酸鹵化物縮合來獲得。合成路線如下示出:化合物I係在茚滿環之3'-碳上具有手性中心之手性分子,其使化合物I具有兩種鏡相異構物形式,即R及S鏡相異構物。進一步研究發現R鏡相異構物係促成殺真菌活性之活性組分,而S鏡相異構物不顯示或顯示較小殺真菌活性。 由此,期望以高產率合成R鏡相異構物之活性組分而不形成不需要之無活性之S鏡相異構物。一個目前使用之用以達成此目標之方法係使用化合物II之R鏡相異構物代替其外消旋形式作為起始物質與相應茚滿衍生物反應,以專門產生所需R鏡相異構物。在此方法之情況下,化合物II之R鏡相異構物係有用的而S鏡相異構物係無用的且遭廢棄。 仍然強烈地需要無活性之S鏡相異構物可再循環且活性R鏡相異構物可以高產率合成。
該需要藉由本發明充分得到滿足。由此,在本發明之一個態樣中,其提供一種用於以(S)-7-氟-1,1,3-三甲基-2,3-二氫-1H-茚-4-胺為起始物質製備(R,S)-7-氟-1,1,3-三甲基-2,3-二氫-1H-茚-4-胺之新穎方法,換言之,一種用於轉換(S)-7-氟-1,1,3-三甲基-2,3-二氫-1H-茚-4-胺為其外消旋形式,即(R,S)-7-氟-1,1,3-三甲基-2,3-二氫-1H-茚-4-胺之方法。 本所主張之方法主要包含以下步驟: (a)醯化(S)-7-氟-1,1,3-三甲基-2,3-二氫-1H-茚-4-胺以獲得茚滿醯胺衍生物; (b)氧化該茚滿醯胺衍生物以獲得3-羥基茚滿醯胺衍生物; (c)使該羥基茚滿醯胺衍生物脫水以獲得茚醯胺衍生物; (d)去醯化該茚醯胺衍生物以獲得茚胺衍生物;及 (e)氫化該茚胺衍生物以獲得所需(R,S)-7-氟-1,1,3-三甲基-2,3-二氫-1H-茚-4-胺。 在本發明之另一態樣中,其提供一種與前述方法充分相同之方法,例外為脫水步驟(c)在去醯化步驟(d)之前或之後進行,或此等兩個步驟同時進行。
