Nitrones have been found to exhibit attractive biological values as immuno spin trapping agents. However, successful clinical cases of nitrone therapeutics are still lacking. Herein we report the synthesis and antiproliferative activity of a series of structurally diverse nitrone derivatives against a panel of 5 cancer cell lines, based on which indole- and pyrrole-fused were further evaluated by analogue preparation and in-vitro screening. Analogues with moderate to good potency were identified. This study shows the promise for further pursuit of nitrone-type small molecules in chemotherapy. [Figure not available: see fulltext.]
A shortcut hydroformylation route to 7-formyl-5,6-dihydroindolizine from 1-allyl-2-formylpyrrole

When 1-allyl-2-formylpyrrole (1) was subject to hydroformylation conditions with Rh4(CO)12 as catalyst precursor, at 100 atm total pressure and 100°C, 7-formyl-5,6-dihydroindolizine (2′) was produced together with the expected branched aldehyde (3), the linear isomer (2) being obtained in traces only. An intramolecular aldol condensation between the carbon atom adjacent to the formyl group in the chain and the carbonyl group directly bonded to pyrrole ring most likely generates the indolizine structure.
DMSO-allyl bromide: A mild and efficient reagent for atom economic one-pot: N -allylation and bromination of 2°-aryl amines, 2-aryl aminoamides, indoles and 7-aza indoles

A mixture DMSO-allyl bromide has been developed as a reagent for an atom economic one-pot N-allylation and aryl bromination under basic conditions. Utilizing this reagent, N-allylation-bromination of a number of 2°-aryl amines, aryl aminoamides, indoles, and 7-aza indoles has been achieved. The scope of the substrates and limitations, the synthetic utility of the products, and a plausible reaction mechanism have been proposed.
