We previously showed that N1-phenyl-3,5-dinitro-N4,N4-di-n-butylsulfanilamide (denoted GB-II-150) possesses selective antimicrotubule activity against Leishmania donovani and Trypanosoma brucei in vitro [Bhattacharya, G., Herman, J., Delfin, D., Sale

The synthesis of C-mannosyl-guanosine 23, an advanced intermediate for the preparation of stable analogues of guanofosfocin, is described. This convergent approach features an improved Traube-type synthesis of a 8-substituted guanine, followed by rib

As a powerful one-electron oxidant, cerium(IV) ammo- nium nitrate (CAN) is useful for a variety of oxidative transforma- tions including carbon-carbon bond formation. Recent work has also demonstrated the usefulness of CAN in carbon-heteroatom bond-f

An efficient synthesis of phenacyl thiocyanates and phenacyl azides is described here. Styrenes react with ammonium thiocyanate and sodium azide in the presence of cerium(IV) ammonium nitrate under an oxygen atmosphere to afford phenacyl thiocyanates

4-Methoxystyrene 1 underwent dimerization to 1,4-diphenylbutane derivatives 5 and 6 in presence of CAN in methanol. But in ethanol the same reaction afforded a tetralone derivative along with 5 and 6. 3,4-Dimethoxystyrene 10 underwent dimerization in

Various 1,3-dienes when treated with a solution of cerium(IV) ammonium nitrate and ammonium thiocyanate in acetonitrile afforded the isothiocyanatothiocyanates via a [3,3] sigmatropic rearrangement. Electron rich dienes afforded the γ-thiocyanato-α
