The development of an intramolecular rhodium(I)-catalyzed Pauson-Khand reaction of alkoxyallene-ynes with a proximal alkoxy group is reported. This reaction, in the presence of a [Rh(cycloocta-1,5-diene)Cl]2/propane-1,3-diylbis(diphenylphosphane) system under a CO atmosphere, constitutes a powerful tool for selectively accessing carbo- and heterobicyclo[5.3.0] frameworks featuring an enol ether moiety. Through this procedure, a straightforward access to guaiane skeletons with a tertiary hydroxy group at the C10 position was achieved.
报道了分子内铑(I)催化的带有近端烷氧基的烯丙基炔与一氧化碳的Pauson-Khand反应的进展。在CO气氛下,该反应在[Rh(环辛-1,5-二烯)Cl]2/丙烷-1,3-二基双(二苯基膦)体系存在下,是选择性获得具有烯醇醚部分的碳环和杂双环[5.3.0]骨架的有力工具。通过该方法,实现了直接获得在C10位带有叔羟基的愈创木烷骨架。
