Abstract
本發明提供大量地以簡便且有效率地製造4,4-二氟-3,4-二氫異喹啉衍生物之方法。一種以通式(1)表示之4,4-二氟-3,4-二氫異喹啉衍生物之製造方法,係使以通式(2)表示之化合物與氟化氫反應;□□
Description
本發明係關於4,4-二氟-3,4-二氫異喹啉衍生物之製造方法。
以防除農園藝用作物之病害為目的已有多數藥劑被提出。例如:專利文獻1及專利文獻2揭示含有以通式(1)表示之4,4-二氟-3,4-二氫異喹啉衍生物
(式中,R1及R2各自獨立地表示也可經取代之碳數1~6之烷基,或R1與R2與此等所鍵結之碳原子成為一體而形成也可經取代之碳數3~10之環烷基,X表示鹵素原子、也可經取代之碳數1~6之烷基、也可經取代之碳數1~6之烷氧基,n表示0~4之整數,Y表示鹵素原子、也可經取代之碳數1~6之烷基、也可經取代之碳數1~6之烷氧基,m表示0~6之整數。)者,該等已知作為農園藝用殺菌劑為有用。所以,以工業規模提供通式(1)表示之化合物之方法係為重要。
但前述專利文未記載上述通式(1)表示之4,4-二氟-3,4-二氫異喹啉衍生物之具體合成法。製造該等化合物群時,利用專利文獻1揭示之將通式(4)表示之異喹啉-4(3H)-酮衍生物之酮基予以脫氧氟化之方法為有效率的。
(式中,R1、R2、X、Y、n及m與前述為同義)。如比較例所示,使用脫氧氟化為代表性之試劑三氟化(二乙胺基)硫((diethylamino)sulfurtrifluoride(參照非專利文獻1)欲與通式(4)表示之化合物進行反應,結果反應進行慢,產率也只有28.9%。又,三氟化(二乙胺基)硫由於反應性高,會有於大量生產時之操作困難的缺點。
於如此的背景下,急切需要開發能簡便地合成4,4-二氟-3,4-二氫異喹啉衍生物且能以工業規模實施生產的製造方法。
