Homochiral (R)- and (S)-3,4-methylenedioxymethamphetamine (MDMA) were prepared in six steps (each) from the chiral pool precursors d- and l-alanine, respectively. The key step, copper-catalysed regioselective ring-opening of an N-tosylaziridine with an aryl Grignard reagent, proceeded in high yield with complete regioselectivity. Elaboration was achieved with preservation of configurational...
