Synthesis and Self-Assembly of Functionalized Donor−σ−Acceptor Molecules
摘要:
3,5,7-Tris(arylmethyl)-1-aza-adamantanetrione donor-alpha-acceptor compounds have been synthesized in four steps. Computational and H-1 NMR analyses rationalize the solubility, gelation, and conformational properties of the C-3-symmetric molecules toward employing sigma-coupled donor-acceptor interactions in molecular self-assembly.

The p-methoxybenzyl protecting group (PMB) on various alcohols and an acid was efficiently and selectively, cleaved by the action of a catalytic amount of silver(I) hexafluoroantimonate combined with 0.5 equiv of 1,3,5-trimethoxybenzene in dichloromethane at 40 degrees C.
