Synthesis of a Novel, Conformationally Restricted Analog of Tryptophan

The synthesis of a new, conformationally restrained analogue of tryptophan, 1,2,3,4-tetrahydro-2-amino-2-carboxy-cyclopentindole (5) is described.The key step involves the BF3*Et2O catalyzed intramolecular cyclization of α-diazoketone 2b into the 1,2,3,4-tetrahydro-cyclopentindol-2-one (3).Key Words: Conformationally restrained tryptophan analog, diazoketone-BF3*Et2O catalyzed intramolecular cyclization, cycloalkindolones.

Rhodium(II) catalyzed intramolecular insertion of carbenoids derived from 2-pyrrolyl and 3-indolyl α-diazo-β-ketoesters and α-diazoketones

α-Diazo-β-ketoesters and α-diazoketones derived from 2-pyrrolylacetic, 2-pyrrolylpropionic, 3-indolylacetic and 3-indolylpropionic acids afforded carbenoid derived cyclization products on treatment with catalytic rhodium(II) acetate.
