diverse functionalized (2-furyl)methylthioether derivatives via base-promoted S-H insertion of conjugated enynones with thiophenols or thiols has been developed. This reaction features readily available starting materials, high atom economy, broad substrate scope, and versatile operation. Moreover, the synthetic utility of this method has been demonstrated by the efficient synthesis of the CNKSPR1 inhibitor

Top cat! Tetrahydrothiophene is an efficient organocatalyst for the synthesis of highlysubstitutedfurfuryl products from readily accessible electron‐poor enynes under neutral reaction conditions. This process is applicable to a wide range of nucleophiles and enynes and can be used in a domino organocatalysis sequence.
A new strategy for facile access to multifunctionalized furans via N-heterocyclic carbene-catalyzed cross-coupling/cyclization of ynenones with aldehydes has been explored. This protocol features readily obtainable starting materials, mild and metal-free conditions, broad substrate scope, good functional group tolerance, excellent yields, and easy scale-up. Synthetic utility of the protocol has been
