Dimethyl sulfoxide (DMSO) has had a long history of use as a polar solvent and active
pharmaceutical ingredient in the past decades. However, in this decade DMSO has attracted …

Dimethyl sulfoxide (DMSO), as extremely important aprotic polar solvent and reaction
medium, has attracted widespread attention from chemists in recent years due to its wide …

An efficient methylthiomethylation of pyrroloisoquinolines and pyrroloquinolines has been
reached by the use of ammonium acetate and dimethyl sulfoxide. Methylthiomethylated …

Thiophene‐based rings are one of the most widely used building blocks for the synthesis of
sulfur‐containing molecules. Inspired by the redox diversity of these features in nature, we …

We have developed an efficient formylation of pyrroloisoquinolines using bromoisobutyrate
and dimethyl sulfoxide as carbonyl reagent. Various formylated pyrroloisoquinolines could …

A [3+ 1+ 1+ 1] annulation of arylamines, arylaldehydes, and dimethyl sulfoxide (DMSO) to
the pyridine structure in quinolines using DMSO as a nonadjacent dual-methine (═ CH−) …

Benzylation of pyrrolo [2, 1-a] isoquinoline derivatives has been realized with various
phenols by the use of ammonium acetate as a promoter (20 examples, up to 84% yield) …

A convenient synthesis of methylene-bridged pyrrolo [2, 1-a] isoquinolines has been
developed. Treatment of pyrroloisoquinolines with acetyl chloride and dimethylsulfoxide …

Metal-free insertion of a methylene group was achieved for the construction of a new C (sp2)–
C (sp3)-H–C (sp2) bond in order to prepare novel bis-heterocyclic scaffolds. The complete …

A convenient preparation method of N-acylbenzoxazines has been developed, in which
phenols react with nitriles and dimethyl sulfoxide (DMSO) in the presence of a catalytic …
