Later in 1971, the discovery of the proline catalyzed Hajos-Parrish-Eder-Sauer-Wiechert reaction brought back the attention of the scientific community to organocatalysis to a small extent because of the importance of this reaction in steroid synthesis [2]. Some other early examples of ...
Co-Catalyst In subject area: Chemistry A co-catalyst refers to a substance that prevents the recombination of charge carriers during the process of splitting water molecules and enhances the rate of photocatalytic water splitting. It can capture holes or electrons and facilitate the redox process, ...
4) Asymmetric alkylation using thiophosphoramidateExamples of using chiral thiophosphoramidate in asymmetric reaction are rare. In this study, asymmetric alkylation of an aldehyde was carried out in the presence of tetraisopropoxy titanium using a thiophosphoramidate (15, PHONE) as the asymmetric c...
