Description:
A monoclonal antibody elicited by a transition-state analog that is representative of an intramolecular six-membered ring cyclization reaction acted as a stereospecific, enzyme-like catalyst for the appropriate substrate. Formation of a single enantiomer of a delta-lactone from the corresponding racemic delta-hydroxyester was accelerated by the antibody by about a factor of 170, which permitted isolation of the lactone in an enantiomeric excess of about 94 percent. This finding demonstrates the feasibility of catalytic-antibody generation for chemical transformations that require stereochemical control.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Napper, A D -- Benkovic, S J -- Tramontano, A -- Lerner, R A -- GM 13306/GM/NIGMS NIH HHS/ -- GM 35318/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1987 Aug 28;237(4818):1041-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3616626" target="_blank"〉PubMed〈/a〉
