Methods: Dalton reaction was employed to produce the synthesis of expoxide from 1-methyl-4-(2, 4, 6-trimethoxyphenyl)-1, 2, 3, 6-tetrahydropyridine, then key intermediate of flavopiridol-piperidol was got by means of AlH3 reduction of expoxide. finally, flavopiridol was prepared via acylation, selective demethylation, adol consendation, chalcone closure, demethylation.
以1-甲基－4-（2，4，6-三甲氧基）－1，2，3，6-四氢吡啶为原料，利用Dalton反应制得环氧，而后经AlH3还原制得Flavopiridol的关键中间体3-哌啶醇，后经拆分、酰化、选择性脱甲基、羟醛缩合、查尔酮氧化关环、脱甲基制得Flavopiridol。

Results There were significant difference of all sperm mobility parameters between normal and abnormal semen groups. As spermatozoa vialibity reduced, VCL, VSL, VAP, MAD, ALH and STR decreased while BCF increased significantly. Compared with the group whose spermatozoa density and activity were both normal, LIN and STR reduced while MAD and BCF increased in the small quantity sperm group. All parameters had significant difference except ALH in the lower sperm activity group. And for the group whose spermatozoa density and activity were both abnormal, only MAD and ALH had no significant difference.
