Barbe, Guillaume; Fiset, Dominic; Charette, Andre B. published the article 《Asymmetric Total Synthesis of (+)-Luciduline: Toward a General Approach to Related Lycopodium Alkaloids》. Keywords: enantioselective synthesis luciduline lycopodium alkaloid Diels Alder cycloaddition metathesis.They researched the compound: (R)-5-Benzyl-2,2,3-trimethylimidazolidin-4-one hydrochloride( cas:323196-43-6 ).Reference of (R)-5-Benzyl-2,2,3-trimethylimidazolidin-4-one hydrochloride. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:323196-43-6) here.
As part of a research program directed toward the synthesis of Lycopodium alkaloids, a multigram scale asym. synthesis of intermediate I was achieved in 11 steps from pyridine. In addition to our alkene metathesis strategy, a key feature of this synthetic approach consists of a Fukuyama’s Diels-Alder cycloaddition between 1,2-dihydropyridine and acrolein using MacMillan’s catalyst on a 50 g scale. This led to a 12-step catalytic asym. synthesis of (+)-luciduline (II). A broader subset of Lycopodium alkaloids could also be obtained, as demonstrated by the derivatization of I into advanced intermediates for the synthesis of some of these natural products.
