Which way? Palladium thiourea catalyzed Pauson–Khand reaction of norbornene with substituted alkynoates to afford selectively either α‐carboxylated adducts or β‐carboxylated adducts with the reverse regioselectivity has been demonstrated for the first time. Control of the regioselectivity in this transformation is governed by the addition of LiCl. A mechanistic interpretation to account for this observed

new gold‐catalyzed annulations of isoxazoles with propiolates have been developed. Most isoxazoles follow an initial O attack on the alkyne to afford a [4+1] annulation product. This process results in a remarkable alkyne cleavage of initial propiolates. Unsubstituted isoxazoles proceed through an N attack step to yield formal [2+2+1]/[4+2] annulation products. These two annulation products arise initially
An electron‐deficient CpE rhodium(III) complex bearing a cyclopentadienyl ligand with two ethyl ester substituents catalyzes the tandem [2+2+2] annulation–lactamization of acetanilides with two alkynoates via cleavage of adjacent two C−H bonds to give densely substituted benzo[cd]indolones. The reactions of meta‐methoxy‐substituted acetanilides with two alkynoates also provided benzo[cd]indolones via
带有环戊二烯基配体和两个乙基酯取代基的缺电子的Cp E铑(III)络合物通过两个相邻的C-H键的裂解来催化[2 + 2 + 2]对乙酰苯胺与两个炔酸的环化-内酰胺化反应取代的苯并[ cd ]吲哚酮。的反应中的元甲氧基-取代的乙酰苯胺具有两个alkynoates还提供了苯并[ CD ]吲哚酮通过相邻的C-H / C-O键的断裂。此外,3,5-二甲氧基乙酰苯胺与两种链烷酸酯反应生成脱芳族的螺环化合物。
