Total syntheses of mitragynine, paynantheine and speciogynine via an enantioselective thiourea-catalysed Pictet-Spengler reaction. Chemical communications (Cambridge, England), 2012, Dec-28, Volume: 48, Issue:100 The pharmacologically interesting indole alkaloids (-)-mitragynine, (+)-paynantheine and (+)-speciogynine were synthesised in nine steps from 4-methoxytryptamine by a route featuring (i) an enantioselective thiourea-catalysed Pictet-Spengler reaction, providing the tetrahydro-β-carboline ring and (ii) a Pd-catalysed Tsuji-Trost allylic alkylation, closing the D-ring.
