Abstract
AbstractA series of enantioenriched 4,5,6,7‐tetrahydrofuro[2,3‐b]pyridines were accessed by a cycloisomerization/cycloaddition strategy. Starting from ynamide derivatives and aldehydes, yields ranging from 27 to 90% and high levels of stereoselectivity (de>95%, 93–99% ee) were obtained through sequential relay catalysis. The concurrent use of a gold complex with a diphenylprolinol silyl ether was applied to a combination of diversely functionalized substrates.magnified image
