The E-TOF will also be feasible and practical to assist chemists in screening the optimal reaction condition or evaluating the overall efficiency of different catalytic systems for a specific asymmetric reaction.4.For the first time,we explored chiralγ-hydroxy-α,β-acetylenic esters,which were prepared via asymmetric alkynylation,as key intermediates to the synthesis of chiralγ-butyrolactones. This convergent and enantioselective approach to chiralγ-butyrolactones is practical and easily handled with protecting group free.

这一概念包括反应产率、对映选择性、配体用量以及反应时间四个重要反应参数，不仅适用同一反应不同催化体系的横向综合性评价，而且适用于某一特定反应催化体系的优化过程，有助于研究人员选择最佳的反应条件。4、我们发展了以手性γ-羟基-α，β-炔酸酯为关键中间体完成了手性γ-丁内酯类天然产物的对映立体选择性全合成，该关键中间体能够以我们的催化体系方便的对映选择性合成，之后的官能团转换方法成熟，易于操作，无需进行繁琐的官能团保护和脱保护过程，绿色经济。

This paper has done a deeply research on the evaluative method, which focus on maintaining and ensuring the camion. After deeply analyzing the maintain theory of army equipment and the stratagem 's characteristic and combining the current systems engineering evaluating theories and methods, it has analyzed and solved all limitations that coming forth when a single model is used to evaluate the maintain capacity. After analyzing and ameliorating the judgment of AHP's coherence, the calculation of the expert power value and the optimizing of the more-extreme judging model, a new calculation method, the multidimensional complex calculation theory, is presented, which much fits for the evaluative calculation of the camion. The new theory's feasibility and the evaluation's reliability have been proved in theory in this paper. This paper also analyses the principle and the program, which is about building a camion evaluating system. According to the multidimensional complex calculation theory, an evaluative model has been built. Applying the levels analytical method, this paper fixes on the calculation of every target's power, brings the optimization allot precept of macro spatial resource, optimizes the resource of the maintainability of theater of operations' vehicle, which offers a theory foundation for optimizing of the resource space. The research not only brings out a uniform standard for the evaluating of the maintain ability of the camion, but also presents a theory foundation and method for perfecting the camion maintain system.
