  Ionic liquid promoted cyclocondensation reactions to the formation of isoxazoles, pyrazoles and pyrimidines

  摘要：

  A simple one-pot procedure to obtain a series of five- and six-membered heterocycles, in three different ionic liquids ([BMIM][BF4], [BMIM][OH] and [HMIM][HSO4]) is described. The synthetic protocol involves the reaction between beta-enamino ketone derived from 1,4-diacetylbenzene and hydroxylamine, hydrazines ((RNHNH2)-N-1, where R-1 = H, Ph, 4-O2N-Ph. 2,4-(O2N)(2)-Ph, C6F5, CO2Me, CONH2, CH2CH2OH, t-Bu) or amidines ((RC)-C-2(NH)NH2, where R-2 = NH2, Ph), furnishing bis-isoxazoles, bis-pyrazoles and bis-pyrimidines in good yields and short reaction times.

  The present invention provides a resin composition capable of forming a film exhibiting a small humidity-dependent variation in optical values; a triazole compound to be incorporated into the resin composition; an optical film and an optical lens, each of which is prepared from the resin composition and exhibits a small humidity-dependent variation in optical values; and a polarizing plate, a circularly polarizing plate, and an image display device, each of which includes the optical film and exhibits excellent moisture resistance. The resin composition of the present invention contains a resin and a compound having a 5-membered or 6-membered aromatic hydrocarbon or heterocyclic ring, wherein the resin is a hygroscopic resin, the compound has at least three specific aromatic rings having a specific NICS value, and the specific aromatic rings are bonded to one another via a single bond or one or two atoms.
