A new series of catechol hydrazines was synthesized and their structure-activity relationship (SAR) was analyzed for developing an effective phosphodiesterase 4 (PDE4) inhibitor as an anti-asthmatic drug candidate. Among the (E)-Analogues tested using in

An asymmetric synthesis of the PDE IV inhibitor, CDP840 (3) is reported. The absolute stereochemistry was controlled by a Jacobsen epoxidation of the Z triaryl olefin 8 (89% ee) or the E triaryl olefin 9 (48% ee). The disparate results in stereocontrol were interpreted in terms of the 'skewed side-on approach model' proposed by Jacobsen. LiBH4 · BH3 reduction of the epoxides was found to proceed with retention of configuration.
