In contrast to the formation of C−O and C−N bonds it was only recently that the selective C−Sbondformation by means of transition metal complexes moved more into the center of research. This is somewhat surprising given the fact that the sulfur atom in a functional group can possess different oxygenation levels which correspond to different chemical properties and reaction portfolios. Herein we wish

Benzosuberene-sulfone (BSS) analogues have been semi-synthesized following green approaches from himachalenes, which has been extracted from essential oil of Cedrusdeodara. In this process, benzosuberene in presence of different aryl or alkyl sodium sulfinates, I2 and potassium persulfate (K2S2O8) in acetonitrile–water solvent conditions gave BSS-analogues at room temperature. Under this reaction
Herein, we describe an efficient and benign protocol for direct C-3 sulfonylmethylation of imidazo[1,2-a]pyridines with glyoxylic acid and sodium sulfinates. Various sulfonylmethylated imidazo[1,2-a]pyridines were synthesized in water under transition metal catalyst-free conditions. This multicomponent reaction featured available substrates, good functional group tolerance, moderate to excellent yields
在这里,我们描述了一种有效且良性的方案,用于直接用乙醛酸和亚磺酸钠对咪唑 [1,2- a ] 吡啶进行 C-3 磺酰甲基化。在无过渡金属催化剂条件下,在水中合成了各种磺酰甲基化咪唑并[1,2 - a ]吡啶。这种多组分反应具有可用的底物、良好的官能团耐受性、中等至优异的产率和温和的反应条件。
