On the synthesis of heterocyclic dendrons

摘要: The synthesis of dendrons 1 - 7 bearing azole (pyrazole, imidazole and 1,2,4-triazole) moieties is described. these compounds was carried out using different approaches: functionalisation the methylene bridge bispirazol-1-ylmethane derivates; double Michael addition 1,2,4-triazole to methyl propiolate, nucleophilic substitution halide from corresponding 2,6-dichloro-4-methylpyridine or 1,3-bis(bromomethyl)benzene derivatives, on p-hydroxybenzaldehyde dimethylacetal. Schotten-Baumann reaction with 1,3,5-trischlorocarbonylbenzene Sonogashira coupling 1,3,5-triethynylbenzene were used for G0-dendrimers.
