The effects of above-mentionedconditions on alkylene reaction are studied to obtain the optimum reactive conditionsby orthogonal experiments having seven factors and three levels. GCLE is chosen as material to prepare 7-phenyl acetamideyl vinyl cephalkyl acidp-methoxy benyl eatsr in the experiment. The process is as follow: GCLE reacts withiodide in solvent, and produce 3-iodid, then reacts with PPh_3 to produce Witting agent,and reacts with HCHO to produce 7-phenyl acetamideyl vinyl cephalkyl acid p-methoxy benyl eatsr in alkaline conditions.

Common buckwheat ( F. esculentum ) is an allogamy crop, which is heterogony. There is heterogeneity in the species. To reveal the genetic diversity within cultivar population, In order to explore the sampling strategy that can reveal genetic diversity of buckwheat resources on the molecular level. PCR with intron-splice junction primers and long random primers was employed to reveal the genetic diversity within nine common buckwheat varieties and one tartary buckwheat cultivar population among different individuals. We established the sampling strategy in its genetic diversity study. Then we used the established sampling strategy, and the same PCR markers technique,to analysis the genetic diversity of 86 common buckwheat resources, the main results are as follows
