(1-nosyl-5-nitroindol-3-yl)methylesters as a novel protective group for carboxylicacid is fully demonstrated. The novel protective group is stable under a broad range of conditions and can easily be deprotected under the mild conditions used for removal of the nosyl (Ns) group. It is orthogonal to the existing protective groups for carboxylicacids such as t-butyl and allyl esters.
Free radical reactions initiated by organocobalt complexes. A new method for the degradation of carboxylic acids tofunctionalised nor-alkanes via acylcobalt salophen intermediates.

1-Triisopropylsilylgramine methiodide reacted smoothly with a variety of nucleophiles in the presence of tetrabutylammmonium fluoride to give 3-substituted indoles. The 3,4-disubstituted indoles were efficiently synthesized by sequential use of 4-selective lithiation of 1-triisopropylsilylgramine and this new substitution reaction.

Flash pyrolysis of dialkylaminopyrroles and thermolysis of 2-pyrrylmethyl phenyl sulfoxide at 65-degrees-C in solution gave azafulvenes which were trapped with a variety of nucleophiles.
