A route to the total synthesis of koumine has been suggested.Five 4-substituted 1,2-dihydropyridine derivatives,which are supposed to be a conjugated diene of Diels-Alder reactionto produce the isoquinuclidine ring of koumine,have been synthesized.Only two of them were foundto be able to undergo the Diels-Alder reaction.The stereochemistry of the reaction product hasalso been examined.
A route to the total synthesis of koumine has been suggested. Five 4-substituted 1,2-dihydropyridine derivatives, which are supposed to be an conjugated diene of Diels-Alder reaction to produce the isoquinuclidine ring of koumine, have been synthesized. Ofly two of the were found to be able to undergo the Diels-Alder reaction. The stereochemistry of the reaction product has been observed.
