A new glycociamidine ring precursor: Syntheses of (Z)-hymenialdisine, (Z)-2-debromohymenialdisine, and (±)-endo-2-debromohymenialdisine
(Chemical Equation Presented) The synthesis of the C11H 5 marine sponge alkaloids, (Z)-hymenialdisine and (Z)-2-debromohymenialdisine, is described. A key step was the condensation between aldisine or its monobromo derivative and a n
