Convergent synthesis of polysubstituted furans via catalytic phosphine mediated multicomponent reactions
Fan, Xia,Chen, Rongshun,Han, Jie,He, Zhengjie
, (2019)
Tri- or tetrasubstituted furans have been prepared from terminal activated olefins and acyl chlorides or anhydrides by a multicomponental convergent synthesis mode. Instead of stoichiometric nBu3P, only catalytic nBu3P or nBu3P=O is needed to furnish the furans in modest to excellent yields with a good functional group tolerance under the aid of reducing agent silane. This synthetic method features a silane-driven catalytic intramolecular Wittig reaction as a key annulation step and represents the first successful application of catalytic Wittig reaction in multicomponent cascade reaction.
Chemoselective C-C bond cleavage of epoxide motifs: Gold(I)-catalyzed diastereoselective [4+3] cycloadditions of 1-(1-Alkynyl)oxiranyl ketones and nitrones

Cutting carbon! A novel facile strategy for the C-C bond cleavage of oxiranyl ketones has been developed. Carbophilic gold(I) activation of the alkyne side chain mediates a heterocyclization and subsequent C-C bond cleavage (see scheme).

Thermal conversion of the endo-peroxides of the arylfurans (1) in a polar aprotic solvent leads to aroylenol esters (4) and diaroyl epoxides (3), the predominance of one over being concentration dependent.The results can be rationalized on the basis of th
