Cobalt-Mediated [2 + 2 + 2]-Cycloadditions: A Maturing Synthetic Strategy [New Synthetic Methods (43)]

2 Synthetic methods Part ( iii ) Protecting groups

Another excellent and comprehensive annual ‘update’ review of the 2000 literature relating to protecting group (PG) strategies in organic synthesis has appeared this year. The employment of PGs to direct ‘docking’ at oxidative enzyme active sites thereby controlling subsequent hydroxylation of unactivated carbon atoms has also been overviewed. Moreover, a summary of the use of microwave (MW) he...

Recent progress in cobalt-mediated [2 + 2 + 2] cycloaddition reactions.

For many years, our research group has been interested in the new developments of cobalt-mediated cyclizations. In this article, our recent achievements in the field of inter- and intramolecular [2 + 2 + 2] cyclizations are compiled.

A new synthetic route to chloride selective [2]catenanes.

A novel anion templation route has been developed to synthesise two new catenanes, which are observed to selectively complex chloride in protic solvent media.

Adsorption of Cu 2 + , Cd 2 + , Pb 2 + and Zn 2 + onto a synthetic Mn oxide

Rh(I)-catalyzed formal [2+2+2] cycloadditions of 1,6-diynes with potassium (Z)-(2-bromovinyl)trifluoroborate: a new strategy and a facile entry to polysubstituented benzene derivatives.

A new strategy for Rh(I)-catalyzed [2+2+2] cycloadditions of 1,6-diynes with potassium (Z)-(2-bromovinyl)trifluoroborate as the third two-atom unit has been realized, which provides a facile entry to polysubstituented benzene derivatives.
