Second, using DBU as the base for enolization of propargylic esters of unsaturated acids 18e-k, we developed a tandem Ireland-Claisen rearrangement /isomerization reactions. It has been shown that the reaction sequence affords triene molecules 42a-b and 43a-b in moderated to high yields. Interestingly, with allyl hexa-3,5-dienoates 18i-j as the substrate, the rearranged products underwent further aromatization to give uniquely substituted benzyl acids 44a-b.

其次，以含有活泼质子的烯酸炔丙酯18e-k为底物，在DBU为烯醇化碱、TMSCl为硅试剂的条件下，底物18e-h发生了Ireland-Claisen重排/异构化串联反应，得到完全共轭的三烯类化合物42a-b及43a-b；而以己二烯酸炔丙基酯18i-j为底物时，重排/异构化后的产物进一步发生电环化等反应最终得到芳构化产物——取代苯甲酸类化合物44a-b。

As the composition of the real wastewaters were always very complicated, deficient of single substrate research was obvious, in view of this , we took a deep examination of Alcaligenes faecalis growth and substrates interaction in phenol and m-cresol mixture.

由于含酚工业废水成份的多样性，单一底物的研究具有明显的局限性，因此，本课题进一步考察了粪产碱杆菌在苯酚和间甲酚混合双底物生物降解系统中的细胞生长及底物降解特性。
