Synthesis of bifunctionalized nitroxyls via intramolecular epoxide ring opening

The syntheses of nitroxyl oxirane and further functionalized derivatives are described. Ring-cleavage reactions of this epoxide have been carried out with a variety of nucleophiles in order to show the general synthetic utility for preparing nitroxyls bearing two functional groups. The relatively facile synthesis of the nitroxyl amino alcohol should prove to be valuable in various spin labeling applications.

Improvement of a critical intermediate step in the synthesis of a nitroxide-based spin-labeled deoxythymidine analog

Methods to reduce the carboxylic acid moiety in 3-carboxy-2,2,5,5- tetramethyl-pyrrolin-1-oxyl to an alcohol as an intermediate toward the corresponding aldehyde have been explored and an improved method has been developed.

Synthesis of nitroxide containing polyenes: two chemically modified retinals and their interaction with bacterioopsin

The synthesis and spectroscopic characterization of two retinal analogues is described, the paramagnetic 3-pyrrolin-1-yloxy analogue 1 and its diamagnetic equivalent, the 3-pyrroline analogue 2.Various aspects of the synthesis of the aminoxy group containing polyenes are discussed.Upon interaction with bacterioopsin, both 1 and 2 are incorporated in the protein and form a system with λmax 459 nm.Neither of the two bacteriorhodopsin analogues is photoactive.ESR spectroscopy data of the system containing 1 show that the ring part of the chromophore in the protein is rigidly fixed in orientation.
