The article was titled 《Regioselective, copper(I)-catalyzed, tandem sulfonylation-cyclization of 1,5-dienes with sulfonyl chlorides》, and you may find the article in Organic Chemistry Frontiers.Category: chlorides-buliding-blocks The information in the text is summarized as follows:
A copper(I)-catalyzed sulfonylation-cyclization of 1,5-dienes with sulfonyl chlorides was developed. This transformation demonstrated a broad substrate scope and presented excellent regioselectivity after radical addition and subsequent deprotonation to form the derivatized 1,5-dihydro-2H-pyrrol-2-one scaffold in one pot. The experimental process involved the reaction of Thiophene-2-sulfonyl chloride(cas: 16629-19-9Category: chlorides-buliding-blocks)
Thiophene-2-sulfonyl chloride(cas: 16629-19-9) is a member of sulfonyl chlorides. Sulfonyl chlorides are reactive sulfonic acid derivatives similar in properties and reactivity to acid chlorides of carboxylates. The sulfonic acid group, however, is a highly hindered molecule, containing a tetrahedral configuration of substituents. Category: chlorides-buliding-blocks
