Synthesis of some New Lariat Ethers as Molecular Motors
the term "nanomotors" refers macromolecules that consume energy in order to perform certain specific cations. nanomachines could play a major role in the future of electronics, medicine and communications. The sulfoxide (1) was prepared by reaction p-cresol with SOCl2 in 65%, bisphonle (2) was prepared with reduction compound (1). Treatment of bisphenole (2) with methyl chloroacetate at refluxed gave dimethyl ester (3) in 98% yield. Macrocycle (4) in 70% yield was prepared by diamidation of diester (3) with diethylentriamine, Lariat ethers (5) and (6) were synthesized by reaction of macrocyle (4) with decasanoylechloride and ecasonoylechloride in 49% and 45% yield.
