AbstractUntil the discovery of catalytic RNA, the notion that all enzymes are proteins had seemed incontrovertible. Now the existence of RNA enzymes has been confirmed in a variety of contexts. What is known about the chemistry of RNA‐catalyzed reactions is reviewed below, with particular attention to the self‐splicing rRNA intron of Tetrahymena ...

HOMOGENEOUS CATALYSIS: ORGANOMETALLIC CATALYSIS AND ORGANOCATALYSIS
Catalysis in Chemistry and Biology, 2018Although soluble catalysts have been used in organic chemistry for many years, until the 1960s they involved simple acids, bases, or metal salts. In most cases, the metals were ignored in any mechanistic considerations. For example, copper salts can catalyze the cyclopropanation of olefins using diazo compounds; however, the role of copper was not ...

The reversible reaction of primary or secondary amines with enolizable aldehydes or ketones affords nucleophilic intermediates, enamines. With chiral amines, catalytic enantioselective reactions via enamine intermediates become possible. In this review, structure-activity relationships and the scope as well as current limitations of enamine catalysis ...
