N- and O-substituted 4[2-diaromaticmethoxy and methylamino)alkyl]piperidines exhibit high CNS activity with respect to the dopamine transporter (DAT) and serotonin transporter (SERT). Preferred compounds exhibit highly differential behavior as between the DAT and SERT and between the DAT and the norepinephrine transporter (NET). The compounds have utility in treating CNS disorders, including but not limited to cocaine addiction, depression, and Parkinson's disease.

diphenylmethyl (DPM) ethers by reaction with O-diphenylmethyl trichloroacetimidate in refluxing toluene without the requirement of a catalyst or other additives. A number of acid and base sensitive substrates were protected in excellent yield using this new method without disturbing the pre-existing functionality present in these molecules. This reaction is the first example of the formation of an ether from stoichiometric
A novel, sustainable, environmentally friendly, solvent-free and metal catalyst-free method for the CDC reaction between NHPI and benzyl/ether compounds is described.
A facile method for the synthesis of O-alkylatedhydroximides through the acid-catalyzed alkylation of hydroximides by using benzylicalcohols as alkylating agents is described for the first time. The obtained O-propargylated products offered easy access to 2,5- and 4,5-dihydroisoxazoles.

N-hydroxyphthalimide and various benzylic and allylic hydrocarbons was realized through an organocatalytic radical-mediated process involving C(sp3)O bond formation using tert-butyl hydroperoxide (t-BuOOH) as an oxidant and tetra-n-butylammonium iodide [(n-Bu]4NI] as a catalyst, during which the phthalimide N-oxyl (PINO) radical and benzylic and allylic radicals were generated in situ and underwent
