This grant in Organic and Macromolecular Chemistry provides                     support for the research of Professor Joseph Gajewski of                        Indiana University. This work is focused on using secondary                     kinetic isotope effects and stereochemistry to determine                        transition state structures in concerted reactions. Strategies                  have also been developed to demonstrate the possible existence                  of intermediates in certain allylic rearrangements. The                         reactions to be studied include 1,3-shifts in the                               vinylcyclopropane rearrangement; 3,3-sigmatropic shifts of                      substrates with strong electron withdrawing groups at C-2;                      ionic 3,3-shifts; 2+2, 2+3, and 2+4 cycloadditions; and                         carbonyl additions.  Attempts will also be made to parameterize                 transition state bond lengths, angles, and constants for                        molecular mechanics calculations of diastereoselectivity in                     pericyclic reactions and carbonyl additions.                                                                                                                    Work of the type supported in this grant is essential if we are                 to understand the dynamics of simple organic reactions. Such                    understanding provides the necessary foundation for studies of                  chemical reactivity in complex molecular systems.
