Title:
SOLID PHASE SYNTHESIS OF ETHER
Document Type and Number:
Japanese Patent JP3130394
Kind Code:
B2
Abstract:

PURPOSE: To selectively obtain an ether compound in high yield by an intramolecular or intermolecular solid phase etherification of a diol derivative or by an intermolecular solid phase etherification of a diol derivative with another alcohol.
CONSTITUTION: An ether compound useful in chemical field is selectively obtained in high yield by carrying out the following etherification in a solid phase: an intermolecular or intramolecular etherification of a diol derivative of formula I [R1 to R4 are H, alkyl or aromatic, wherein at least one of R1 to R4 are aromatic or tertiary alkyl; R1 and R2, R3 and R4 or R2 and R3 may together form CH2-Y-CH2 (Y is CH2, O, etc.); X is (CH2)n ((n)=1-5), (C≤C)m ((m)=1-3), formula II or formula III] (e.g. a compound of formula IV) or an intermolecular etherification of a diol derivative of formula I and another alcohol (e.g. ethanol or benzhydrol). This etherification gives an ether compound even from a bulky alcohol in high yield. This etherification also enables to selectively synthesize an acyclic ether compound by an intermolecular etherification of a diol derivative with another alcohol.
