3,4,5-Triarylisothiazoles via C-C coupling chemistry
(2007)The regiocontrolled preparation of triarylisothiazoles is presented. 3-Halo-5-phenylisothiazole-4-carbonitriles, 1 (hal = Cl) and 18 (hal = I), are converted into the corresponding 4-bromo derivatives 5 (3-hal = Cl) and ...

Macrocyclic malonates. A new family of tethers for the regio- and diastereoselective functionalization of [60]fullerene
(2006)The tether-directed remote functionalization of C60 has been investigated by using cyclic bis- and trismalonate tethers. The reactive malonate groups are connected with alkyl spacers and their synthesis was performed in ...

Remote functionalization of C60 with enantiomerically pure cyclo-[2]-malonate tethers bearing C12 and C14 spacers: Synthetic access to bisadducts of C60 with the inherently chiral trans-3 addition pattern
(2013)In this Article, we describe the synthesis of two optically pure diols bearing a 1,2-diol moiety masked as an isopropylidene acetal group and long alkyl chains comprised of 12 and 14 carbon atoms, respectively. The synthetic ...
