High-pressure Approach to the Synthesis of N,N'-Dimethyl Diazacoronands

α,ω-Tertiary diamines react under high pressure with α,ω-di-iodo compounds to give the cyclic bis-quaternary salts in almost quantitative yields and their subsequent demethylation with triphenylphosphine affords N,N'-dimethyl diazacoronands in high yield.

Efficient Synthesis of N,N'-Dimethyl Diazacoronands

Modification of the Richman and Atkins method for preparation of symmetric and nonsymmetric bis-(p-toluenesulphonyl) diazacoronands is reported.The one-pot transformation of these compounds into N,N'-dimethyl diazacoronands is also described.
