A family of aryl-substituted maleimides was prepared and studied for their activity against calmodulin dependant kinase. Inhibitory activities against the enzyme ranged from 10 nM to >20 μM and were dependant upon both the nature of the aryl group a

We have investigated the cobalt mediated PausonKhand (PK) reaction in water. In the presence of detergents and surfactants, Co2(CO)8 and Co4(CO)12 are effective under aqueous-phase, thermal PK reactions. In a waterTriton®X-100 medium, Co4(CO)12

We investigated the formation of macrocycles from alpha,omega-diynes in cobalt-mediated co-cyclotrimerization reactions. Long-chain alpha,omega-diynes underwent metal-mediated [2 + 2 + 2] cycloadditions with nitriles, cyanamides, or isocyanates in th

NMO-promoted room temperature cyclizations of the cobalt carbonyl complexes of substrates bearing terminal and internal alkynes gave exclusively the Pauson-Khand (PK) reaction adducts in a water-Triton X®-100 medium.

High levels of diastereoselection were achieved in the PKR of 1,6- and 1,7-cyclopropylidenynes bearing a bulky propargylic C(2)-symmetric acetal.

Efficient stoichiometric Pauson–Khand reactions were realized in water as the only solvent, and in the presence of surfactants as additives. Use of the cationic surfactant CTAB provided good yields of cyclopentenones from the thermal reactions of p

In this report we have shown that the commercially available Co(2)(CO)(8) and Co(4)(CO)(12), and enyne--Co(2)(CO)(6) complexes, are sufficiently effective in catalyzing the Pauson--Khand reaction under one atmosphere of CO pressure. It was further de

The dicobalthexacarbonyl alkyne complex of a series of enynes templated on aromatic rings has been shown to undergo the Pauson–Khand reaction to generate medium-sized rings.
