求翻译：synthesized by means of Wittig–Horner reactions between appropriate dibenzyloxybenzylphosphonic acid diethylesters(5a,b) and benzyloxybenzaldehydes (6a-c), followed by deprotection using AlCl3 and N,N dimethylaniline as outlined in Scheme 2. Trans geometries of these compounds were confirmed by their coupling constants是什么意思？ 待解决
