  Regioselective Carbolithiation of o-Amino-(E)-Stilbenes:  Cascade Route to the Quinoline Scaffold

  摘要：

  The regioselective carbolithiation of substituted ortho-amino-(E)-stilbenes can be exploited to initiate cascade reaction sequences that can be utilized as new routes to substituted 3,4-dihydro-1H-quinolin-2-ones,1,2,3,4-tetrahydroquinolines, 1,4-dihydroquinolines, and quinolines.

  [GRAPHICS]A regioselective carbolithiation of o-amino-(E)-stilbenes has been achieved with a series of alkyllithiums when THF is employed as the reaction solvent. The use of other solvents, such as diethyl ether or hydrocarbons, leads to a pronounced loss in regioselectivity. Moreover, high levels of diastereoselectivity have been obtained following reaction of the lithiated intermediate in THF with different electrophiles such as MeOD, CO2, and Bu3SnCl. It was shown that diastereoselectivity was influenced by the ortho-amino substituent and the alkyllithium utilized for carbolithiation with N-Boc substituent and t-BuLi proving optimal. In the case of carbolithiated intermediate 3a, obtained from the reaction of N-Boc substituted stilbene with t-BuLi, H-1 and C-13 NMR analysis revealed predominantly one diastereoisomer which was stable at room temperature. Application of the carbolithiation/electrophile reaction methodology to the synthesis of six-membered quinoline ring systems is demonstrated with substituted 3,4-dihydroquinolin-2-ones, 1,2,3,4-tetrahydroquinolines, 1,4-dihydroquinolines, and quinolines all prepared by a common cascade route.
