Research Interests: Due in large part to the development of new reagents, chemists today have the ability to routinely carry out . Yields of cyclobutane adducts of up to 94% and with 99% diastereoselectivity have been achieved. High diastereoselectivity is obtained in all cases and the use of chiral aldehydes affords Felkin products when there are non-chelating substituents, chelation products when there is a chelating sbustituent and syn products when there is b-substitution. Due in large part to the development of new reagents, chemists today have the ability to routinely carry out syntheses which would have been impossible to carry out a few decades ago.
