Synthesis of Phenoxy Amide Derivatives

Several kinds of new derivatives of N-substituted-4-(p-chlorophenoxy)acetamide and N-substituted-2,4-dichlorophenoxy acetamide were synthesized with methyl chloroacetate. The influence of solvent on the chlorination occurred in the benzene ring of phenoxy acetamide additives has been investigated by using sulfonyl chloride as chlorination agent. Result shows that the higher polarity of solvent is beneficial to the chlorination.

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.
