Methods and materials for preparing 4-substituted-2-buten-4-olides are disclosed. The methods include reacting a masked mucohalic acid with a primary or secondary amine or with an arylol in the presence of a base. Unlike existing processes, the disclosed methods do not require the use of palladium, which make them well suited for preparing intermediates in drug syntheses.

An efficient copper(I)/proline sodium salt‐catalyzed alkyl‐ and arylsulfenylation of C(sp2)–X 3,4‐dihalo‐2(5H)‐furanone compounds with sulfoxides is described. For inexpensive C(sp2)–Cl compounds, there is also a satisfactory reactivity with the moderate yields. This transformation provides a novel approach for the utilization of sulfoxides (not only DMSO) as sulfur source at mild temperatures without

series of (E)-N-2(5H)-furanonyl sulfonyl hydrazone derivatives have been rationally designed and efficiently synthesized by one-pot reaction with good yields for the first time. This green approach with wide substrate range and good selectivity can be achieved at room temperature in a short time in the presence of metal-free catalyst. The cytotoxic activities against three human cancer cell lines of all
