cycloaddition reactionsVinyl ketenes, generated from the dienoic acids (I), (V), (VIII), and (XI) via their acid chlorides, undergo intramolecular cycloaddition to produce the fused cyclobutanones (II), (VI), and (VII), (IX) and (X) or (XII) and (XIII) as shown in the reaction ...
近日,南方科技大学李闯创教授课题组,在国际知名期刊《Nature Communications》上以“Facile generation of bridged medium-sized polycyclic systems by rhodium-catalysed intramolecular (3+2) dipolar cycloadditions”为题,首次报道了铑催化的Type ...
Things are too long away now for introducing any change, but one should remember that using Norrish name here is a mistake, while it would be appropriate to add the name of Ciamician for a different name reaction, the 2 + 2 cycloaddition of alkenes and conjugated carbonyls. In 1968, such...
