Abstract:

Ytterbium(III) triflate has been utilized as a mild Lewis-acid catalyst for the synthesis of various calix[4]pyrroles by the condensation of pyrrole with different ketones in ionic liquids. The calix[4]pyrroles were obtained in high yield under ecofriendly, economical, and noncorrosive conditions, and the catalyst was recovered and recycled.Key words: calix[4]pyrrole, ionic liquid, ytterbium triflate.

Abstract:

The addition of indole and methyl indole at both high and ambient pressures to a series of Michael acceptors under the influence of ytterbium triflate was investigated. Under ambient pressure the more reactive and less sterically hindered electrophiles gave the expected 3-alkylated indoles in good to excellent yields. The more problematic Michael acceptors were subjected to pressures of 13 kbar. In all cases a dramatic reduction in reaction time and a significant improvement in yields was observed. In the cases involving 3-methylcyclohex-2-en-1-one, a by-product was formed and was characterize

Most of the cases the assembly is directed by the H-bonding interaction as well as the interaction of alkali metal ion with the guanosine molecules. Herein we report the synthesis of a new bipyridyl substituted guanosine molecule G5 which forms a tris bipyridyl ruthen

碩士<br>輔仁大學<br>化學系<br>100<br>This thesis uses aromatic aldehydes 3a－e to react with benzylamine to prepare arylimines 4a－e. Compounds 4a－e underwent imino Diels－Alder reactions with Danishefsky’s diene in the presence of Yb(OTf)3 catalyst to give products 1a－e. In order to increase the reaction efficiency, we tried many different conditions for compound 4a, and found that 30 mol% of Yb(OTf)3 in refluxing acetonitrile provided the best yield of 1a in 81%. With this optimized condition and slight variation of the amount of the Yb(OTf)3, the yields of 1b－e were also improved. Furthermore, we use

Abstract:

碩士<br>國立中興大學<br>化學系所<br>107<br>The concept of orthogonality has become a mainstream for development of building blocks to carbohydrate synthesis. In this work, we developed two new orthogonal protecting groups for carbohydrates, namely 4-Acetoxybenzyl Carbonate (ABC) and 2-(Acetylsulfanyl)methyl Benzoate (ASMB). Both of them can be efficiently installed into different carbohydrate glycosides. Moreover, the two protecting groups can be selectively removed using Ytterbium(III) trifluoromethanesulfonate [Yb(OTf)3] under mild reaction conditions. The ABC group was selectively removed by deprotecti
