Dynamic combinatorial library for fullerene receptors based on metal-assisted self-assembly
摘要:
A dynamic combinatorial library was prepared by the metal-induced self-assembly of phenanthroline derivatives having a guest binding unit. The binding assay using ESI mass spectrometry found out the effective combination of guest binding units for fullerene binding. (c) 2006 Published by Elsevier Ltd.
A simple method for the synthesis of 1,3-dioxolanes from carbonyl compounds has been developed using 1,2-bis(trimethylsilyloxy)ethane in the presence of bismuth(III) triflate as a catalyst. The bismuth(III) triflate catalyzed synthesis of a range of dioxanes and dioxepines has also been developed. In these latter cases, the carbonyl compound is treated with a diol, and triethyl orthoformate is used as a water scavenger. All these methods avoid the use of a Dean-Stark trap.

A series of diformylbenzophenones were generated by sequentially reacting protected bromobenzaldehydes with n-butyllithium and ethyl N,N-dimethylcarbamate. The acetal protective groups were cleaved with refluxing formic acid. Vilsmeier–Haack formylation of 2,2′,4,4′-tetramethoxybenzophenone also afforded a related dialdehyde.
