A new access to spiro[5.5]undecane frameworks was reported through the ZnMe2-promoted alkynylation of salicylaldehyde and HCO2H-mediated dearomatizative cyclization which can be used to construct an all-carbon quaternary spirocenter. This method can be applied to the rapid synthesis towards a series of useful motifs of natural products, such as the core of elatol and aphidicolin.

A new copper(I)-catalyzed cycloetherification followed by an acid-catalyzed allylic nucleophilic substitution have been developed for the one-pot synthesis of 2-substituted benzofurans. This one-pot reaction proceeds efficiently under extremely mild conditions with simple and inexpensive catalysts, providing diversely substituted benzofurans in good to excellent yields.

One thing leads to another: Bis(benzannelated) 5,6-spiroketal skeletons can be constructed by an efficient cascade process involving an unprecedented CuI-catalyzed intramolecular alkyne hydroalkoxylation and an asymmetric hetero-Diels-Alder cyc
