7-Benzoyloxy-3-(2-nitrophenylseleno)-1,5-cyclodecadiyne (13) was prepared from 5-hexyn-1-ol and propargyl bromide via 10-iodo-7-(t-butyldiphenylsiloxy)-5,9-decadiynal (10). The facile cyclization of the acyclic precursor 10 would be rationalized in terms of "bulky group (TBDPSO) assisted conformational control". Oxidation of 13 by NaIO4, followed by thermal

A short and efficient synthesis of cinnoline-fused cyclic enediyne is reported. Richter cyclization of o-(1,3-butadiynyl)phenyltriazene produced 3-alkynyl-4-bromocinnoline. The Sonogashira coupling of the latter with 5-hexyn-1-ol was employed for the introduction of a second acetylenic moiety. The crucial cyclization step was

The first total syntheses of the Lycopodium alkaloids (+)-nankakurine A (2), (+)-nankakurine B (3), and the originally purported structure 1 of nankakurine A were accomplished. The syntheses of 2 and 3 feature a demanding intramolecular azomethine imine cycloaddition as the

Four novel 1,2,3-triazolium-functionalized starch derivatives were synthesized by N-alkylating the precursor starch derivatives with 1,2,3-triazole with iodomethane based on cuprous-catalyzed azide-alkyne cycloaddition (CuAAC). The detailed structural characterization was investigated by means of FTIR, UV-vis
