Transition States of Vicinal Diamine-Catalyzed Aldol Reactions.
The transition states of aldol reactions catalyzed by vicinal diamines are characterized with density functional calculations. It was found that a cyclic transition state involving a nine-membered hydrogen-bonded ring is preferred. The crown (chair-chair) conformations of the transition state accoun...
