Unusual Approach to Branched 3-Alkynylamides and to 1,5-Dihydropyrrol-2-ones
摘要:
Rare carboxamide branched alkynes such as 11a can be readily obtained by reaction of the electrophilic 4-alkylidene isoxazolinones with isocycanides followed by nitrosative cleavage of the heterocyclic ring. N-lodosuccinimide induced ring closure in the presence of a nucleophile results in the formation of new iodopyrrolinones such as 16c.
An unprecedented silver‐catalyzed difunctionalization of the isocyanogroup with cyclicoximes is described. This method allows efficient and atom‐economic assembly of a vast array of structurally novel and interesting pyrimidinediones, and tolerates a range of functionalities. The resulting products can be easily converted into some useful compounds. Furthermore, the method can also be applied for

the nitrogen and carbons atoms of the isocyanogroup would largely enrich the structural diversity of compounds. Herein, we disclosed a silver-catalyzeddifunctionalization of the isocyanogroup with cyclicoximes. This method can generate a great array of structurally novel and interesting pyrimidinediones and features excellent atom economy, good functional group compatibility, and amenability to late-stage
