Selective reduction with Cp(sub.2)ZrHCl
Article Abstract:
Selective reduction with bis(cyclopentadienyl)zirconium chloride hydride, Cp(sub.2)ZrHCl, is discussed by a graduate reserach student and a faculty member, both at the Dept. of Medicinal Chemistry, University of Kansas, Lawrence, and a senior research scientist in the medicinal chemistry division of Coelacanth Corp. Functional group manipulation is critical in synthetic organic chemistry. Tertiary amides are convenient intermediates in multistep organic syntheses, but difficult to remove selectrively. The hydrozirconium reagent discussed is suitable. Topics include reduction to aldehydes, scope and selectivity, establishing the mechanism, and advantages of Cp(sub.2)ZrHCl.

Furan as a versatile synthon
Article Abstract:
This article describes usage of the aromatic heterocyclic furan in the organic synthesis of diverse and innovative complex molecules. Furan, a bis(enol ether), exhibits synthetic diversity and is used in the synthesis of compounds such as fastigilin-C, gibberellins, and in various electrochemical synthetic reactions of polymers and oxabicyclooctane derivatives.
