中文摘要：

向到终端炔属羟的 2,2-dihydroxybiphenyl 的周期的增加的合成策略作为催化剂用路易斯酸 TiCl4 被开发了。反应产生了 dibenzo [d， f ][1,3 ] 在有优秀 regio 选择的好收益的 dioxepines 衍生物面对在温和反应条件下面的 TiCl4 的催化数量。

英文摘要：

A synthetic strategy toward the cyclic addition of 2,2＇-dihydroxybiphenyl to terminal alkynes has been developed using Lewis acid TICl4 as catalyst. The reactions generated dibenzo[d,f][1,3]dioxepines derivatives in good yields with excellent regio-selectivity in the presence of catalytic amount of TICl4 under mild reaction conditions.
