Photochemical Decatungstate‐Catalyzed Hydroacylation of Maleimides
European Journal of Organic Chemistry, EarlyView.A photocatalytic protocol to access substituted succinimides via tetra‐n‐butylammonium decatungstate photocatalysis is reported. This direct radical‐driven hydroacylation of a variety of N‐substituted maleimides shows tolerance to various aldehydes (or alkanes), affording differentially substituted succinimides in high yields. Succinimides constitute a

European Journal of Organic Chemistry, EarlyView.A cascade reaction under phase‐transfer conditions between 3‐nitro indoles and isocyanomethylene dibenzenes affords the construction of pyrrolo[3,4‐b]indole cores. Control experiments provide insight into moderate product yields and clarify why the reaction is not amenable to asymmetric induction. A cascade reaction enabling the construction of pyrrolo[

In silico design of 2,2'-dihydroxybenzophenones and xanthone analogues to inhibit human glutathione transferase's (hGSTs) involvement in Multiple Drug Resistance. [PDF]
, 2015 Glutathione S-transferases catalyze the conjugation of glutathione (GSH) to a variety of hydrophobic substrates, rendering them hydrophilic and facilitating their metabolic processing and secretion from the cell. GSTs are involved in major detoxification
