  Synthesis and evaluation of photophysical properties of Series of π-conjugated oxazole dyes

  摘要：

  Incorporation of pi-conjugated spacers at the 2 or 5 position of a 2,5-disubstitutedaryloxazole led to new series of fluorescent dyes. They show emissions from visible to 700 nm along with significant Stokes shift up to 208 nm and a strong solvatochromic fluorescence. These compounds are easily accessible in one step through direct C-H bond functionalization. (C) 2013 Elsevier Ltd. All rights reserved.

  A copper-catalyzed direct alkenylation of oxazoles with bromoalkenes has been developed. The method is both regio- and stereoselective and tolerates a variety of functional groups. A wide range of 2-E-vinyl-substituted oxazoles were obtained in high yields including the highly fluorescent alkaloid annuloline.
