Novel bicyclo[3.1.0]hexanyl purine nucleoside analogues were synthesized as potential antiherpetic agents via a bicyclo[3.1.0]hexanol (${\pm}$)-8, which was prepared using a highly efficient carbenoid cycloaddition reaction. A highly diastereoselective reduction of ketone and a Mitsunobu reaction for the condensation of glycosyl donor (${\pm}$)-12 with 6-chloropurine were employed.

We synthesized various catechol ether type derivatives substituted by the hydrazine moiety and evaluated for their ability to inhibit PDE Ⅳ (Phosphodiesterase Ⅳ). These new compounds were synthesized from 4-methoxy-3-hydroxy benzaldehyde through 5 or 7 steps. Some of them have similar or more potent inhibitory activity against PDE Ⅳ than known PDE Ⅳ inhibitor. Ariflo (SB 207499). Structure activity relationship (SAR) and biological studies of described compounds will be discussed in detail. (omitted)
