Here, we demonstrate that the first example of 3 isothiocyanato thiobutyrolactone serving as an useful building block in Michael/cyclization reaction with alkylidene pyrazolones for the enantioselective construction of optically active...

Developing efficient methods for preparing the privileged chiral ligands is an important endeavor in synthetic chemistry. Herein, we develop an effective, modular method for synthesis of tertiary amine-derived C2-symmetric chiral...

Herein, a highly efficient strategy that allows the diversity synthesis of a library of structural bispiro[butyrolactone-pyrrolidine-indanedione] hybrids is achieved effectively by means of 1,3-dipolar cycloadditions of α,β-unsaturated butyrolactones/valerolactones as dipolarophiles...

The first example of 3-vinyl oxindole-chromones in the ring opening and recyclization reaction.

Herein is reported the first example of ring opening and skeletal reconstruction of 3-vinyl benzofuranone-chromones 1 as versatile synthons for the synthesis of functionalized 2-pyridones 3 in good to excellent yields.
