SYNTHESIS OF 3-HYDROXYSPERMIDINE: AN UNUSUAL POLYAMINE CONSTITUENT OF CYTOTOXIC MARINE COMPOUNDS
Ponasik, James A.,Ganem, Bruce
, p. 9109 - 9112 (2007/10/02)
A short, convergent synthesis of the title compound, (+/-)-N1-(3-aminopropyl)-1,4-diamino-2-butanol 6, was accomplished in 42percent overall yield by means of a highly regioselective 1,3-dipolar nitrone cycloaddition.
