In this thesis, a convenient and efficient synthesis of highly functionalizeddihydropyrido[2,3-d]pyrimidines via a double [5 + 1] annulation strategy startingfrom easily available α-alkenoyl-α-carbamoyl ketene--acetals 1 and cheapreagents (NH4OAc, DMF, and POCl3) has been developed.

本论文探索了一种简便有效的合成高度官能化的二氢吡啶并[2，3-d]嘧啶的方法，此方法由易得的α-乙酰基-α-氨基乙酰基二硫缩烯酮1和便宜的试剂(醋酸铵，二甲基甲酰胺和三氯氧磷)通过两步[5 + 1]加成而实现。

The annulation of stilbene compounds were studied. Phenanthrene derivates-interme diates of tylophorine were synthesized by annulation from-2,3-bis(3,4-dimethoxyphen yl)acrylic acid and-2,3-bis(3,4-dimethoxyphenyl) acrylonitrile with phenyliodine diace tate as a friendly and high efficient catalyzer.The route was first reported, whose application foreground would be promising.The catalyzer will be used to study of synthesi- zing a series of new phenanthrenes.

本文还探索了简单类化合物关环反应，并研究出用廉价高效对环境友好的催化剂-二乙酸碘苯成功地将类化合物－3，4-二甲氧基-α-(3，4-二甲氧苯基)-肉桂酸和-2-(3，4-二甲氧苯基)-3-(3，4-二甲氧苯基)-丙烯关环形成相应的菲环衍生物－娃儿藤碱重要中间体，此方法在国内尚属首次，具有重要的应用价值，此外可用此催化剂研究一系列类化合物的关环反应。

E. Cummings, Malcolm Cowley, and many other novelists, dramatists, poets, and critics who tried to find their souls in the Antibes and on the Left Bank, who directed sad and bitter blasts at their native land and who, almost to a man, drifted back within a few years out of sheer homesickness, to take up residence on coastal islands and in New England farmhouses and to produce works ripened by the tempering (they lived there and got a kind of practice in critical thinking) of an older, more sophisticated society.
