The synthesis of dibenzofuran based diacids and amino acids designed to nucleate parallel and antiparallel β-sheet formation.
摘要:
4-(N-tert-butyloxycarbonyl-2-aminoethyl-)-6-dibenzofuranpropionic acid (1) and 4,6-dibenzofurandipropionic acid (2) designed to nucleate antiparallel and parallel beta-sheet formation, respectively, have been synthesized in multi-gram quantities.

Right said thread: Oxidativeintramolecularcoupling reactions of α,ω‐diynes in the presence of macrocyclic phenanthroline CuI complexes allows the synthesis of [2]catenanes in up to 64 % yield (see scheme). The bond‐forming reaction leads to concurrent threading of the diyne through the phenanthroline macrocycle.
