  TiCl₄, Dioxane—A Facile and Efficient System for De-O-Benzylation, De-O-Allylation, and De-O-Xylylation of Phenolic Ethers

  摘要：

  Simultaneous de-O-xylylation and reductive coupling was observed when I equiv. of the dialdehyde 2a/2b was treated with 5 equiv. of each TiCl4 and Zinc which lead to the development of TiCl4 in dioxane as a new system for the facile deprotection of phenolic ethers 4a-4d, 5a-5d, and 6a-6c.

  1-Butyl-3-methylimidazolium chloroaluminate, [bmim] Cl center dot. AlCl3 (molar fraction, N = 0.67), ionic liquid has been used in combination with metallic Zn for the reductive coupling of carbonyl compounds to synthesize symmetrical olefins, with the Z-isomer formed predominantly. The ionic liquid played a dual role of Lewis acid catalyst and solvent.

  It is an object of the present invention to provide an allergen suppressor exerting an effect of suppressing an allergen under humidities normally used, and an allergen-suppression processed fiber, which can suppress an allergen adhering to fibers automatically without applying an allergen-suppression process and a method of producing the same. That is, the present invention is an allergen, suppressor, which contains a hydrophilic polymer and a component suppressing an allergen.
