Wang, Shuiliang published the artcileFacile synthesis of methylthiomethyl esters through Pummerer-type rearrangement of carboxylic acids and DMSO under metal-free conditions, Safety of (E)-3-(3-Nitrophenyl)acrylic acid, the publication is Synthetic Communications (2019), 49(7), 950-958, database is CAplus.
A green and cost-effective Pummerer-type rearrangement between readily accessible carboxylic acids and DMSO has been achieved under metal-free conditions in satisfactory to excellent yields. The transformation for the synthesis of valuable methylthiomethyl esters is shown to be a convenient strategy for various (hetero)aromatic acids, ¦Á,¦Â-unsaturated carboxylic acids and saturated alkyl carboxylic acids with good functional group tolerance.
Synthetic Communications published new progress about 1772-76-5. 1772-76-5 belongs to catalysis-chemistry, auxiliary class Benzenes, name is (E)-3-(3-Nitrophenyl)acrylic acid, and the molecular formula is C27H39ClN2, Safety of (E)-3-(3-Nitrophenyl)acrylic acid.
