Chemistry of the hexahydropyrrolo [2, 3-b] indoles: Configuration, conformation, reactivity, and applications in synthesis
Article Abstract:
The stereoselective formation of 2-endo-substituted hexahydro-pyrrolo[2,3-b]indoles from 2-substituted tryptamine derivatives, particularly tryptophan, is described and compared with the formation of related heterocyclic systems like hexahydrofurano[2,3-b] benzofurans. Their reactivity and use in the stereocontrolled synthesis of amino acids and alkaloids are presented.

Ultrafast 2D IR vibrational echo spectroscopy
Article Abstract:
An experimental technique and application of ultra fast two-dimensional infrared (2D IR) vibrational echo spectroscopy are provided. The examinations of processes that cannot be studied with linear infrared absorption experiments are permitted by the form and time evolution of the 2D IR spectrum.

Generation of cycloalkynes by hydro-iodonio-elimination of vinyl iodonium salts
Article Abstract:
The efficient and mild generation of cyclohexynes and cycloheptynes via two types of reactions of iodonium salts is presented. Cyclohexyne is generated by hydro-iodonio-elimination of the cyclohexenyl iodonium salt while cycloheptyne forms from cyclohexylidenemethyl iodonium salt.
