Alkylation of cyclic ketones and α-methoxycarbonyl ketones with 4-iodo-2-trimethylstannylbut-1-ene and/or 5-iodo-2-trimethylstannylpent-1-ene, and subsequent (Ph3P)4Pd-catalysed cyclization of the enol trifluoromethanesulphonates derived form the alkylation products, from the basis of new annulation sequences which result in the formation of diene systems.
环酮和α-甲氧基羰基酮与4-碘-2-三甲基锡烷基丁-1-烯和/或5-碘-2-三甲基锡烷基戊-1-烯的烷基化反应,以及随后的(Ph 3 P)4 Pd催化的环化反应烯醇三氟甲烷磺酸酯是根据新的环化顺序而形成的烷基化产物,该环化导致形成二烯系统。
