One-pot synthesis of protected homoallyl amines

Allyltrichlorosilanes reacted with benzoylhydrazones in DMF without the use of any catalyst to afford the corresponding homoallylic benzoylhydrazines in good to high yields. The reactions proceeded at 0 °C to room temperature under mild conditions. In addition, it was found that the reactions tolerated well the steric hindrance of hydrazones and allyltrichlorosilanes. Indeed, ketone-derived benzoylhydrazones reacted with allyltrichlorosilane smoothly to afford the corresponding N‘-tert-alkyl-N-benzoylhydrazines in high yields. In crotylation with (E)- and (Z)-crotyltrichlorosilanes, syn- and anti-adducts were stereospecifically obtained, respectively. These reactions are most likely to proceed via a cyclic chairlike transition state where the R group takes an axial position. When α-heteroatom-substituted chiral benzoylhydrazones were used, high anti-diastereoselectivities were observed. These adducts can be readily converted to homoallylic amines in high yields without epimerization.

The first synthesis of a water-soluble α-cyclodextrin/C60 supramolecular complex using anionic C60 as a building block

Herein we report the spectroscopic, electrochemical, TEM and DLS characterizations of C60 supramolecular inclusion complexes with α‐, β‐and γ‐cyclodextrins prepared using anionic C60. The results indicate that the cyclodextrin itself has little effect on the encapsulated C60 or on the properties of the inclusion complex. Instead, the cyclodextrin has a significant influence on the aggregation behavior of individual complex in aqueous solution, which in turn affects the property of the supramolecular complex of cyclodextrin and C60 greatly. As the cavity dimension of cyclodextrin becomes smaller as it changes from γ‐CD to β‐CD, and finally to α‐CD, it is observed that more aggregation occurs for the corresponding inclusion complex in aqueous solution.

Study of α‐, β‐and γ‐Cyclodextrin/C60 Supramolecular Complexes: Influence of the Cavity Dimension toward the Host‐Guest Complexes

A novel supramolecular inclusion complex of alpha-CD/C-60 was synthesized using anionic C-60. The reaction progress was monitored in situ by visible and near-IR spectroscopy. The obtained complex was characterized by UV-vis, C-13 NMR, MALDI-TOF, and cyclic voltammetry. The induction and dispersion forces are considered to be the major driving forces for the formation of a resulting alpha-CD/C-60(.-) inclusion complex.
