• attention in recent years because of their broad biological activities [11][12] and therapeutic applications, ranging from antibiotics [13] to anticancer agents [14]. Moreover, the DKP moiety has been exploited as a peptidomimetic scaffold [15][16][17]. Structural unification of THBC and DKP pharmacophores

• well as in increasing solubility [20]. Moreover, triazoles can function as attractive linker units which could connect two pharmacophores to give an innovative bifunctional drug, and thus have become increasingly useful and important in constructing bioactive and functional molecules [21][22][23

• derivative 62 (Scheme 12), which contains aldehyde, carboxylic acid and hydroxymethyl groups as pharmacophores. The dihedral angles of CHO-CH2-CH2-COOH in the cyclopentane analog are very close to those of the carbon skeleton in sordaricin. The synthesis of 62 started with commercially available (+)-3,9
