The Zr-catalyzed kinetic resolution of aliphatic allylic ethers derived from five-, six-, seven-,
and eight-membered ring allylic alcohols is reported. The level of resolution efficiency varies …

The present studies arose from our interest in the enantioselective synthesis of 2-substituted
chromenes, 1 a structural unit found within a myriad of medicinally important agents. 2 In this …

This letter reports our successful use of the Grubbs ruthenium imidazole alkylidene catalyst
in enol ether–olefin ring closing metathesis reactions.© 2000 Published by Elsevier Science …

Homoallyl‐substituted vinyl cyclopropanes 1a‐c, which are readily prepared by reaction of
allylindium reagents with α, β‐unsaturated ketones and aldehydes, undergo Ru‐catalysed …

Subsequent reports by Hoye and co-workers [3] and by Mori and co-workers [4] on
analogous Mo-and Cr-based carbene precatalysts also invoked mechanism A, which neatly …

Ring-opening metathesis (ROM) of various unsaturated, constrained bicyclic ring systems
has been investigated with the use of commercial ruthenium-based catalysts. Starting from …

The ring-closing metathesis (RCM) of acyclic dienes in both methanol and water has been
achieved through the use of water-soluble ruthenium alkylidenes. These alkylidenes react …

This report details the kinetic responses of nine compounds of type 6 to ring-closing
metathesis as promoted by 2 to give the identical product 7. The experimental observations …

The Mo-catalyzed asymmetric ring-closing metathesis (ARCM) of various achiral trienes
leads to the formation of medium-ring unsaturated heterocycles in high yield and with …

Publisher Summary The chapter presents advances in the field of ring-closing metathesis
(RCM) as applied to the synthesis of heterocyclic compounds. Emphasis is placed on the …
