  METHOD FOR PRODUCING COMPOUND HAVING ACID-LABILE GROUP

  摘要：

  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）。

  The present invention provides a process for producing a compound having a group represented by general formula (II). (wherein R 1 , R 2 , and R 3 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 R 1 and R 2 may bind to each other to form an alicyclic hydrocarbon ring together with the adjacent carbon atoms, or R 2 and R 3 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 R 1 , R 2 , and R 3 are the same as those defined above, respectively and X represents a halogen atom).
