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。

We concluded that uroflowmetry was a simple, non-invasive procedure which provided an objective evaluation of the uroflow in hypospadias. Urethral stricture after urethroplasty could be diagnosed with uroflowmetry. The low flow rate in congenital hypospadias was mainly due to meatal stenosis. Oral mucosa graft combined with a local flap for hypospadias repair provided satisfactory functional results.

我们推论：尿流率测定评价尿道下裂患者排尿功能，方法简便，准确可靠，对尿道下裂术后尿道狭窄具有诊断意义；先天性尿道下裂患者尿流率曲线多数呈平台形，最大尿流率降低，其主要原因为尿道外口狭窄；口腔粘膜片移植与局部皮瓣耦合组建尿道修复尿道下裂功能性效果良好。
