A visible-light photoredox catalyzed radical cascade cyclization of simple ethers with cyanamides is developed at room temperature. This strategy involves sequential inert Csp3-H/Csp2-H functionalizations through intermolecular addition reaction of oxyalkyl radicals to N-cyano groups followed by radical cyclization of iminyl radicals in situ generated with C-2 aryl rings. This method allows for efficient synthesis of tetracyclic benzo[4,5]imidazo[1,2-c]quinazolines. Importantly, this is the first example of an intermolecular-intramolecular radical cascade cyclization reaction of cyanamides.

In this study, we designed a library of compounds based on the structures of well-known ligands of the 18 kDa translocator protein (TSPO), one of the putative components of the mPTP. We performed diverse mitochondrial functional assays to assess their ability to restore cells from Aβ-induced toxicity in vitro and in vivo. Among tested compounds, compound 25 effectively improved cognitive function in animal models of AD. Given the excellent in vitro and in vivo activity and a favorable pharmacokinetic profile of compound 25, we believe that it can serve as a promising lead compound for a potential treatment option for AD.

Propylphosphonic anhydride (T3P) has been demonstrated to be an efficient and mild reagent for the one-pot synthesis of benzimidazoles and benzothiazoles from variety of alcohols. Mild conditions, short reaction time, broad functional group tolerance, low epimerization, easy and quick isolation of the products, excellent chemo selectivity, and excellent yields are main advantages of this procedure. Thus, the present method is utilizing alcohols instead of aldehydes.
