Direct observation of metalated N,N-dimethylbenzylamines by ft NMR spectroscopy

Direct observation of the respective ortho and benzylic metalated N,N-dimethylbenzylamines by 13C and 1H FT NMR spectroscopy has been achieved. NMR assignments and the effect of temperature on the 13C resonances are reported. Evidence for an essentially trigonal benzylic carbon in α-potassio-N,N-dimethylbenzylamine is presented.

The Synthesis of 2,7-Dioxabicyclo[3.2.1]Octanes

Abstract Intramolecular acetals are prevalent in natural products including frontalin, exo and endo-brevicomin and other insect pheromones.1 Recently, a substituted 2,7-dioxabicyclo[3.2.1]-octane was employed as an intermediate in the total synthesis of the insect poison dl-pederamide.2 In this paper we wish to report on an efficient synthesis of 2,7-dioxabicyclo[3.2.1]octanes.
