An attempt to utilize a new strategy for alkaloid synthesis which features the intramolecular [4+2] cycloaddition of enamines and enamides for the construction of the tetracyclic spiroamine skeleton characteristic of the ~rythrina alkaloids was unsuccessful, unexpectedly giving a bridged cycloadduct
Cyclic 2-thiomethyl-5-amidofurans possessing tethered p-bonds were prepared by a dimethyl(methylthio) sulfonium tetrafluoroborate (DMTSF) induced cyclization of various amido dithioacetals. Upon heating, these systems undergo an intramolecular 4+2-cycloaddition reaction. The initially formed Diels-A
