(Chemical Equation Presented) The microwave-promoted Suzuki coupling reaction of aryl chlorides with boronic acids performed in an aqueous media was studied using the air- and moisture-stable catalyst POPd2 (dihydrogen di-μ-chlorodichlorobis(di-test-butylphosphinito-κP)dipalladate (2-)). This catalyst system under microwave conditions (150°C, 15 min) provided coupled products with yields ranging from 64% to 99%. This method tolerated a variety of substituents and sterically hindered substrates.

A full account of the total synthesis of aspidostomide B, C, their analogues and our synthetic efforts towards the synthesis of aspidostomide D, which led to the synthesis of regioisomeric N-methyl aspidostomide D, its analogues via epoxide opening strategy is presented. The synthesis of regioisomeric N-methyl aspidostomide D involves an efficient, five-step sequence, with 36.3% overall yield, starting from 3,4,5-tribromo-1H-pyrrole-2-carboxylic acid. The key features of this protocol are intramolecular cyclization, dehydration, oxidation, and a Lewis acid-mediated regioselective epoxide ring opening by C-3 position of 2,5-dibromo-1H-indole to furnish the title compounds.
