New bis(aza-crown ethers) comprising aza-crown ether and diaza-crown ether interconnected by carbon arm connecting the nitrogen atom of aza-crown ether and nitrogen atoms of diaza-crown ether, useful as phase transfer catalyst

摘要

Bis(aza-crown ethers) (Q) are new. (Q) comprise aza-crown ether and diaza-crown ether interconnected by at least one carbon arm connecting the nitrogen atom of the aza-crown ether and one of the nitrogen atoms of the diaza-crown ether, where second nitrogen atom of diaza-crown ether comprises hydrogen or carbon chain. Bis(aza-crown ethers) (Q) of formula (I) or (II) are new. (Q) comprise aza-crown ether and diaza-crown ether interconnected by at least one carbon arm connecting the nitrogen atom of the aza-crown ether and one of the nitrogen atoms of the diaza-crown ether, where second nitrogen atom of diaza-crown ether comprises hydrogen or carbon chain. X1, Y1 : H or carbon chain having 1-4 atoms; m : 1, 2, 3, 4, 5 or 6 (preferably 3 or 4); n : 1, 2 or 3 (preferably 1 or 2); p : 1, 2 or 3 (preferably 2); y : 5-30 (preferably 16-26); and Z : 3, 4, 5, 6, 7, 8, 9 or 10 (preferably 3, 4, 5 or 6). Independent claims are included for: (1) an intermediate compound comprising bis(aza-crown ethers) of formula (IV), (V) or (VII); and (2) preparing (Q). GP : amine protecting group. [Image] [Image].
