Sherer, E. C.; Turner, G. M.; Lively, T. N.; Landry, D. W.; Shields, G. C. A Semiempirical Transition State Structure for the First Step in the Alkaline Hydrolysis of Cocaine. Comparison between the Transition State Structure, the Phosphonate Monoester Transition State Analog, and a Newly Designed Thiophosphonate Transition Stat. J. Mol. Model. 1996, 2 (4), 62-69.
Semiempirical molecular orbital calculations have been performed for the first step in the alkaline hydrolysis of the neutral benzoylester of cocaine. Successes, failures, and limitations of these calculations are reviewed. A PM3 calculated transition state structure is compared with the PM3 calculated structure for the hapten used to induce catalytic antibodies for the hydrolysis of cocaine. Implications of these calculations for the computer-aided design of transition state analogs for the induction of catalytic antibodies are discussed.
