Enantioselective organocatalysis
Drug Discovery Today, 2007Enantioselective organocatalysis has emerged as a powerful synthetic paradigm that is complementary to metal-catalysed transformations and has accelerated the development of new methods to make diverse chiral molecules. The operational simplicity, ready availability of catalysts and low toxicity associated with organocatalysis makes it an attractive ...

This chapter provides a guide to the use of organocatalysis as a general catalytic concept in synthetic chemistry and aims to demonstrate the fundamental ideas and reasoning that lie behind the most popular strategies in this area. The key to the rapid growth in this field within the least two decades lies in an improved understanding of the different ...

Organocatalysis is a new and fast growing research area, especially for asymmetric synthesis. Compared to metal catalysis and biocatalysis, organocatalysis has a number of unique features such metal-free, mild reaction conditions, novel mode of activations, and good structural amenability. Fluorous organocatalysis provides an efficient way for catalyst

Organocatalysis Combined with Photocatalysis
Topics in Current Chemistry, 2019Over the past decade, the combination of visible light photocatalysis and organocatalysis has made remarkable progress in modern chemical synthesis. In these dual catalysis system, photocatalysts or photosensitizers absorb visible light to induce their photoexcited states which can activate unreactive substrates via electron or energy transfer ...
