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 FIRST TOTAL SYNTHESIS OF TAXAMAIRIN B Taxamairin B, representive of rare naturally-occuring rearrang-ed 9(10→20)-abeo-8, 11, 13-triene diterpenoids, has been firstsynthesized by a eleven-step route in an overall yield of 8.19%,starting from commercially available catechol and 1,3-cyclohexan-dione. The improved Friedel-Crafts annulation, thermodynamicallycontrolled-geminal pairing methylation, the selective oxidation ofallyl group and the selective reduction of the less-hindrancecarbon-carbon double bond are the key steps.
