Organic chemists have always been fascinated by the cyclopropane subunit. 1 The smallest
cycloalkane is found as a basic structural element in a wide range of naturally occurring …

This review provides a critical analysis of catalytic kinetic resolution reactions from a
practical perspective, asking the question of when, if ever, is kinetic resolution the best …

The world is chiral. Most of the molecules in it are chiral, and asymmetric synthesis is an
important means by which enantiopure chiral molecules may be obtained for study and sale …

In 1966 Nozaki, Moriuti, Takaya, and Noyori reported the first enantiocontrolled catalytic
intermolecular cyclopropanation reaction. l Using a salicylaldimine ligand for copper (II) that …

Rhodium-catalyzed reactions of tertiary propargylic alcohols with methyl aryl-and
styryldiazoacetates result in tandem reactions, consisting of oxonium ylide formation …

3, 5-Di t Bu-QingPhyrin, a new D 2-symmetric chiral porphyrin derived from a chiral
cyclopropanecarboxamide containing two contiguous stereocenters, has been developed …

In a competition experiment where a 1: 1 mixture of two substrates reacts simultaneously
with a single reagent, the initial product ratio corresponds to the inherent selectivity s (the …
