| 요약 | Hydrogen bonding exhibits its importance in enzyme-catalyzed chemical transformations, naturally occurring three-dimensional architectures and molecular recognition. In recent years, synthetic chemists have successfully exploited hydrogen bonds |
| 요약 | Thiourea derivatives are among the most common and widely-developed hydrogen bond catalysts. Impressive results in terms of both yields and enantioselectivities in asymmetric syntheses have been obtained. A key feature in their success is the ab |
| 요약 | The work described in this thesis focuses on the development of a class of positively charged acidity-enhanced thiourea catalysts which make use of an alkylated pyridinium substituent and an appropriate non-coordinating counteranion to enhance t |
