Areas of Specialization

Synthetic Organic Chemistry and the Development of New Reagents for Ultrasensitive Analysis of Bioactive Molecules


Research Interests

Organic chemistry: organic synthesis, natural products, highly strained ring systems, photochemistry and bioanalytical chemistry

Professor Carlson's research focuses primarily in the area of synthetic organic chemistry, new synthetic methods, strained-ring systems, photochemistry, natural products and bioanalytical chemistry.

As part of our effort to develop new synthetic methodology we have been investigating the chemistry of the highly strained methylenecyclopropane system as a building block of more complex molecules. We have developed methods by which the methylenecyclopropane group can be introduced into a variety of molecules by way of organometallic intermediates. Our most recent studies have involved the preparation of highly strained oxaspiropetanes by expoidation of substituted methylene-cyclopanes with dimethyldioxirane and an examination of their rearrangements with a variety of Lewis or protic acids. Some typical results are shown below:

In connection with work in the Center for BioAnalytical Research (CBAR) we have been engaged in an extensive program directed at the design and synthesis of new tagging reagents which will permit the detection and ultrasensitive quantitative analysis of bioactive molecules by fluorescent, chemiluminescent and electrochemical methods. This work involves extensive collaboration with chemists in other areas of chemistry. We have developed a series of substituted 2, 3- naphtahalenedicar-boxaldehyde reagents which react selectively with primary amines to give highly fluorescent derivatives. The imidazole substituted system shown is of current interest for laser-induced fluorescence detection in capillary electrophoresis studies.

The substituted hydroquinone reagent shown has been prepared and preliminary studies indicate that it will be very useful for electrochemical detection at very low levels.
