Then the cyclocarbonylation of propargylic alcohols under the catalysis of Pd 〓 with CuBr〓 and BQ was studied. Due to the high activity the yields of -α-bromoalkylidene-β-lactones were lower than that of -α-chloroalkylidene-β-lactones while the coupling reaction of -α-bromoalkylidene-β-1actones (i. e. Sonogashira and Suzuki coupling reaction) was quite smooth to afford the products in high yields.

接着我们研究了炔丙醇在Pd〓-CuBr〓-BQ催化体系下的羰基插入环化反应，由于-α-溴代亚烷基-β-内酯环化合物的活性高于-α-氯代亚烷基-β-内酯环化合物，导致反应收率偏低，而同样基于此原因，-α-溴代亚烷基-β-内酯环化合物的偶联反应进行得很顺利，而且收率很高。

In this paper, the basic chromophores of flavonoid and pyrazolone dyes were chosen and subjected to be modified, then polyamino crosslinking groups were introduced into the prepared intermediates to afford cros...
