An efficient asymmetric synthesis of (-)-Lupinine
Chem Commun (Camb) 2014 Aug 7;50(61):8309-11.PMID:24938152DOI:10.1039/c4cc02135e.
The asymmetric synthesis of (-)-Lupinine was achieved in 8 steps, 15% overall yield and >99 : 1 dr from commercially available starting materials. The strategy used for the construction of the quinolizidine scaffold involved reaction of an enantiopure tertiary dibenzylamine via two sequential ring-closures which both occurred with concomitant N-debenzylation.
Short access to (+)-Lupinine and (+)-epiquinamide via double hydroformylation
Org Lett 2010 Feb 5;12(3):528-31.PMID:20038131DOI:10.1021/ol902718q.
Short and efficient access to (+)-Lupinine and (+)-epiquinamide by means of an unprecedented double hydroformylation of a bis-homoallylic azide followed by a tandem catalytic hydrogenation/reductive bis-amination is reported.
Rotational spectra of bicyclic decanes: the trans conformation of (-)-Lupinine
J Phys Chem A 2013 Dec 19;117(50):13673-9.PMID:24028578DOI:10.1021/jp407671m.
The conformational and structural properties of the bicyclic quinolizidine alkaloid (-)-Lupinine have been investigated in a supersonic jet expansion using microwave spectroscopy. The rotational spectrum is consistent with a single dominant trans conformation within a double-chair skeleton, which is stabilized by more than 10.4 kJ mol(-1) with respect to other conformations. In the isolated conditions of the jet, the hydroxy methyl side chain of the molecule locks in to form an intramolecular O-H···N hydrogen bond to the electron lone pair at the nitrogen atom. Accurate rotational constants, centrifugal distortion corrections, and (14)N nuclear quadrupole coupling parameters are reported and compared to ab initio (MP2) and DFT (M06-2X) calculations. The stability of lupinine is further compared computationally with epilupinine and decaline in order to gauge the influence of intramolecular hydrogen bonding, absent in these molecules.
Regioselective Asymmetric Alkynylation of N-Alkyl Pyridiniums
Org Lett 2021 Sep 3;23(17):6703-6708.PMID:34474575DOI:10.1021/acs.orglett.1c02276.
Disclosed in this Letter is a novel asymmetric addition of alkynyl nucleophiles to N-alkylpyridinium electrophiles. The coupling is effected under mild and simple reaction conditions, affording dihydropyridine products with complete regiochemical and stereochemical control. In addition to several manipulations of the dihydropyridine products, the utility of this transformation is demonstrated through a concise, dearomative, and asymmetric synthesis of (+)-Lupinine, a natural acetylcholine esterase inhibitor.
Synthesis and comparison of antiplasmodial activity of (+), (-) and racemic 7-chloro-4-(N-lupinyl)aminoquinoline
Bioorg Med Chem 2012 Oct 1;20(19):5980-5.PMID:22901673DOI:10.1016/j.bmc.2012.07.041.
Recently the N-(-)-lupinyl-derivative of 7-chloro-4-aminoquinoline ((-)-AM-1; 7-chloro-4-{N-[(1S,9aR)(octahydro-2H-quinolizin-1-yl)methyl]amino}quinoline) showed potent in vitro and in vivo activity against both Chloroquine susceptible and resistant strains of Plasmodium falciparum. However, (-)-AM-1 is synthesized starting from (-)-Lupinine, an expensive alkaloid isolated from Lupinus luteus whose worldwide production is not sufficient, at present, for large market purposes. To overcome this issue, the corresponding racemic compound, derived from synthetic (±)-lupinine was considered a cheaper alternative for the development of a novel antimalarial agent. Therefore, the racemic and the 7-chloro-4-(N-(+)-lupinyl)aminoquinoline ((±)-AM-1; (+)-AM-1) were synthesized and their in vitro antimalarial activity and cytotoxicity compared with those of (-)-AM-1. The (+)-lupinine required for the synthesis of (+)-AM-1 was obtained through a not previously described lipase catalyzed kinetic resolution of (±)-lupinine. In terms of antimalarial activity, (±)-AM1 and (+)-AM1 demonstrated very good activity in vitro against both CQ-R and CQ-S strains of P. falciparum (range IC(50) 16-35 nM), and low toxicity against human normal cell lines (therapeutic index >1000), comparable with that of (-)-AM1. These results confirm that the racemate (±)-AM1 could be considered as a potential antimalarial agent, ensuring a decrease of costs of synthesis compared to (-)-AM1.
