The dissertation mainly consists of two parts:1. The Reaction Chemistry of Alkynes under Palladium Catalysis Part 1 studies the reaction α,β-unsaturated carbonyl compounds with alkenylpalladium intermediate generated by nucleopalladation, and discovered 1 the Pd-catalyzed tandem addition reaction of halides, alkynes and α,β-unsaturated carbonyls,2 the four-component tandem addition reaction of halides, alkynes and α,β-unsaturated carbonyls, 3 the tandem intramolecular oxypalladation-conjugate additionreaction of alkynoic acids with α,β-enals. These new reactions provide notonly efficient highly stereoselective methods for the synthesis of γ,δ-unsaturated,polyunsaturated carbonyl compounds and γ-lactonic aldehydes, but also thebasic transformations for a number of C-C bond formation reactions which can be usedto design synthesis of many acyclic, cyclic or polycyclic compounds.

本论文的主要工作分为两个部分：一、钯催化下炔烃的反应化学在本小组前人工作的基础上，我们详细研究了炔烃亲核钯化产生的烯基钯中间体与α，β-不饱和羰基化合物的反应，发现两价钯催化下卤离子-炔烃-α，β-不饱和醛酮的串联加成反应、卤离子-炔烃-α，β-不饱和醛酮的西组分串联加成及炔酸分子内氧钯化-串联Michael型加成反应；由此发展了γ，δ-不饱和醛酮、多不饱和羰基化合物和带有醛酮基侧链的γ-丁内酯衍生物的高立体选择性合成方法，这一过量卤离子存在下的烯基钯对α，β-不饱和羰基化合物共轭加成反应的发现，为大量碳-碳键形成反应的实现提供了基础，使我们能够从这一基本反应出发，设计和开发多种分子内、分子间的碳碳成键反应，以好的立体、区域选择性组建开链、环状及多环类型的化合物。
