英文摘要 | The Rh-II-carbene reaction is dramatically affected by the neighboring substituents. If the neighboring substituent is an OH group, a1,2-H shift is the exclusive pathway. If it is an OAc group, a 1,2-acetoxy migration is observed. If it is p-toluenesulfonyl group, 1,3 and 1,5-C-H insertion are the major pathways, and the 1,2-H shift is completely suppressed. If the adjacent substituent is a trichloroacetyl amino group, 1.,5-C-H insertion competes with the 1,2-hydride shift, and no 1,3-C H insertion can be observed. Both electronic and steric factors are responsible for the switching of the Rh-II-carbene reaction pathway. The highly stereoselective 1,5-C-H insertions in Rh-II-catalyzed reaction of alpha-diazocarbonyl compounds, bearing beta-trichloroacetylamino substituent, can be utilized as a novel way to synthesize five-membered cyclic beta-amino acid derivatives.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000277724800012&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Chemistry, Multidisciplinary; SCI(E); PubMed; 11; ARTICLE; 5; 1112-1119; 5 |
