Abstract :
The first convergent and non-protective synthesis of a G-2 melamine dendrimer having (1S,2S)-1,3-dihydroxy-1-(4-nitrophenyl)-prop-2-ylamino units as peripheral groups (from l-p-nitrophenylserinol) and piperazine as linker is described to occur in five linear steps and 27 % overall yield. The restricted rotation about Csp2(s-triazine)-N(exocyclic) bonds, exhibited by all compounds, is discussed as relevant.
