7-芳亚甲基异长叶烷酮类化合物的合成及其紫外吸收特征
Synthesis and ultraviolet absorption characteristics of 7-arylidene-isolongifolanene
摘要
Abstract
A series of 7⁃arylidene⁃isolongifolanone a—j were synthesized by condensation of isolongifolanone with aro⁃matic aldehydes including 4⁃bromobenzaldehyde, 4⁃fluorobenzaldehyde, 3⁃nitrobenzaldehyde, 2,4⁃dichlorobenzaldehyde under catalyzation of potassium tert⁃butoxide. The structures of compounds a—j were identified by means of 1 H NMR, 13 C NMR, GC⁃MS and FT⁃IR, and their ultraviolet absorption characteristics as well as light stabilities were also investi⁃gated. The results showed that compounds a, b, c, d and j exhibited good absorbency as the medium⁃wave ultraviolet ( UVB) type absorbents,and compounds e, f, g, h and i had both functions as long⁃wave ultraviolet ( UVA) and UVB absorbents. The light stability sequence of those compounds was h>g>e>c>a>d>b>f>i>j. The UV absorption intensity was d>i>e>h>g>f>b>c>j>a.关键词
