Dimethylammonium dimethylcarbamate (DIMCARB) was used as both catalyst and reaction medium for the synthesis of monoarylidenes cycloadduct intermediates, which were further used to produce diarylidene cyclohexanones. All 34 compounds synthesized were evaluated for their anti-proliferative activity, particularly against promastigote of Leishmania amazonensis, epimastigote and trypomastigote of Trypanosoma cruzi. Eighteen compounds displayed anti-leishmanial activity against promastigotes of L. amazonensis with IC50 values ranging from 2.8 to 10 μM. In addition, two compounds exhibited significant antitrypanosomal activity against epimastigotes of T. cruzi with IC50 values of 5.2±0.8 and 3.0±0.0μM, while five compounds exhibited activity from 15.0±1.4 to 30.2±1.8μM against trypomastigote of T. cruzi. Moreover, all compounds were more selective against the parasites than the epithelial cells. The unsym. compounds II [R1 = R2 = H, R3 = MeO, R4 = 2,3-(MeO)2C6H3; R1 = R2 = MeO, R3 = H, R4 = 4-O2NC6H4, 3,4,5-(MeO)3C6H2, 3,4-(MeO)2C6H3] can be considered as favorable anti-parasitic lead mols. having IC50 and EC50 values in the low-micromolar range, better than the reference drug benznidazole, and low cytotoxicity against Vero cells.

Then, the hydroxyl groups of HPG on graphene oxide were functionalized by sulfonate groups to form an acid catalyst. The catalyst displayed a good loading level of acidic groups on the surface because of coating graphene oxide with HPG. This new catalyst is demonstrated to be highly effective in the preparation of benzo[a]pyrano[2,3-c]phenazine dyes.

Calogero, Francesco published the artcileDiastereoselective and enantioselective photoredox pinacol coupling promoted by titanium complexes with a red-absorbing organic dye, Safety of 1,3-Dimethoxybenzene, the main research area is aryl aldehyde enantioselective diastereoselective photoredox pinacol coupling; bis aryl ethane diol preparation.

A highly diastereoselective pinacol coupling reaction of aromatic aldehydes promoted by 5 mol% of the non-toxic, inexpensive and available Cp2TiCl2 complex. The key feature that allowed the complete control of diastereoselectivity was the employment of a red-absorbing organic dye in the presence of a redox-active titanium complex. Taking advantage of the well-tailored photoredox potential of this organic dye, the selective reduction of Ti(IV) to Ti(III) was achieved. These conditions enable the formation of the D,L (syn) diastereoisomer as the favored product of the pinacol coupling (d.r. > 20 : 1 in most of the cases). Moreover, employing a simply prepared chiral SalenTi complex, the new photoredox reaction gave a complete diastereoselection for the D,L diastereoisomer and high enantiocontrol (up to 92% of enantiomeric excess).
