A facile synthesis of tetrahydrobenzo[b]furans via gold(I)-catalyzed cycloisomerization of 1-aryl-2-propargylcyclohex-2-enols is described. The transformation is suggested to proceed through a gold(I)-catalyzed tertiary allylic alcohol rearrangement to gi

A mild and efficient dual-mode Lewis acid induced Diels-Alder (DA)/carbocyclization cascade cyclization reaction has been developed for construction of the tricyclic core of ent-kaurenoids in one pot with the aid of a theoretical study on the π,σ-Lewis acidities of a variety of Lewis acids. With ZnBr2 as the dual-mode Lewis acid, a series of substituted enones and dienes underwent DA/carbocyclization cascade cyclization reaction smoothly at room temperature and provided the tricyclic cyclized products in one pot with good yields and high diastereoselectivity. The tricyclic cyclized product has been successfully utilized as a common intermediate for formal syntheses of (±)-platensimycin and (±)-platencin.

An efficient procedure for α-alkylation of cyclohex-2-enone and cyclopent-2-enone involving a base-promoted tandem of retrograde Dieckmann-Michael reactions of the C-alkylated derivatives of the title heterocycles is presented.
