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
据报道,在分子内铑(I)催化下,烷氧基丙二烯-炔与近端烷氧基基团发生了Pauson-Khand反应。在CO气氛下,在[Rh(环辛基-1,5-二烯)Cl] 2 /丙烷-1,3-二基双(二苯基膦)系统存在下,该反应构成了有选择地接触碳环和杂双环的强大工具[5.3.0]以烯醇醚部分为特征的骨架。通过此程序,可以直接访问C10位置带有叔羟基的愈创树骨架。
