Quinolizidine and dipiperidine alkaloid profiles have been determined for various plant parts of ten papilionaceous species in the tribes Sophoreae, Dalbergieae, Brongniartieae and Bossiaeeae.Alkaloids have been identified for the first time from species in the tribes Dalbergieae (Dalbergia monetaria) and Brongniartieae (Harpalyce formosa var. formosa) of Polhill's classification system of the Papilionoideae.No alkaloids were detected in seeds of several Lotus species (tribe Loteae).Quinolizidine-indolizidine alkaloids of the leontidine type, including 11-epileontidane, a new compound, were obtained from the leaves and stems of Maackia amurensis. 11,12-Dehydrosparteine, a compound which has not previously been characterized as a natural product, was observed in an extract of the stems of Templetonia egena. - Key Word Index - Papilionoideae; tribes Sophoreae, Dalbergieae, Loteae, Brongniartieae, Bossiaeeae; Leguminosae; chemotaxonomy; quinolizidine alkaloids; 11-epileontidane; 11,12-dehydrosparteine.
Gram-Scale Synthesis of the (?)-Sparteine Surrogate and (?)-Sparteine

An 8-step, gram-scale synthesis of the (?)-sparteine surrogate (22 % yield, with just 3 chromatographic purifications) and a 10-step, gram-scale synthesis of (?)-sparteine (31 % yield) are reported. Both syntheses proceed with complete diastereocontrol and allow access to either antipode. Since the syntheses do not rely on natural product extraction, our work addresses long-term supply issues relating to these widely used chiral ligands.
