Substrate specificity and enantioselectivity of 4-hydroxyacetophenone monooxygenase. Title Creator Subject Faculty Date.

The objective of the research described in this thesis is to both understand the reactivity of these dipoles, and exploit their cycloaddition with alkynes and alkenes to synthesize pyrroles and 2-pyrrolines with high regio- diastereo- and enantioselectivity. While each of the dipoles are established to participate in 1,3-dipolar cycloaddition reactions, until now, le general rules regarding the factors that control regioselectivity have been described.

These 1,3-dipoles have been previously demonstrated to be accessible in a one-pot reaction of imines, acid chlorides and organophosphorus reagents, and participate in 1,3-dipolar cycloaddition reactions.

Importantly, these 1,3-dipoles display divergent regioselectivity, which can be exploited to synthesize a variety of pyrroles with high selectivity through the use of the appropriate reactant. In Chapter 5, a new way to control the enantioselectivity in 1,3-dipolar cycloaddition reactions is described.
