α,γ-Peptide Nanotube Templating of One-Dimensional Parallel Fullerene Arrangements
摘要:
The formation and full characterization of single self-assembling alpha,gamma-peptide nanotubes (alpha,gamma-SPNs) is described. The introduction of C-60 into cyclic peptides allows the preparation of supramotecular 1D fullerene arrangements induced by peptide nanotube formation under appropriate conditions.

Multicomponent Cascade Reactions of Unprotected Ketoses and Amino Acids – Access to a Defined Configured Quaternary Stereogenic Center
摘要:
A highly stereoselective multicomponent cascade reaction of ketones with unprotected amino acids was developed. This operationally simple methodology was expanded to reactions of unprotected ketohexoses and unprotected amino acids. By the careful choice of amino acid and isonitrile, an optional access to all possible enantiomers is given.

the Zhdankin reagent to styrene‐typedoublebonds, and subsequent addition of a third component to the benzylic position. In the presence of light, a photoredox cycle is implicated with polar components such as methanol or bromide adding to a benzylic cation. In the absence of light, by contrast, doubleazidation takes place to give diazides. Therefore, regioselective double functionalization can be
