The present invention provides a process for producing a compound having a group represented by general formula (II):
(wherein R1, R2, and R3 may be the same or different, and each represent a substituted or unsubstituted alkyl, a substituted or unsubstituted aryl, or a substituted or unsubstituted aralkyl, or R1 and R2 may bind to each other to form an alicyclic hydrocarbon ring together with the adjacent carbon atoms, or R2 and R3 may bind to each other to form a alicyclic heterocyclic ring together with the adjacent O-C-C that may have a substituent), which comprises allowing a compound having a hydroxyl group to react with halogenated alkyl ether represented by general formula (I):
(wherein R1, R2, and R3 are the same as those defined above, respectively and X represents a halogen atom).
本发明提供了一种生产具有由通式(II)表示的基团的化合物的方法:(其中R1、R2和R3可以相同也可以不同,并且分别表示取代或未取代的烷基、取代或未取代的芳基、或取代或未取代的芳基烷基,或者R1和R2可以相互结合形成与相邻碳原子一起的脂环碳氢环,或者R2和R3可以相互结合形成与相邻的O-C-C一起具有取代基的脂环杂环)的方法,该方法包括允许具有羟基的化合物与由通式(I)表示的卤代烷基醚发生反应:(其中R1、R2和R3分别与上述定义相同,X代表卤素原子)。
