Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 1452-77-3, is researched, SMILESS is O=C(N)C1=NC=CC=C1, Molecular C6H6N2OJournal, Article, Journal of Organic Chemistry called Hypervalent Iodine Reagent-Promoted Hofmann-Type Rearrangement/Carboxylation of Primary Amides, Author is Wang, Xia; Yang, Peng; Hu, Bo; Zhang, Qian; Li, Dong, the main research direction is secondary amide preparation; primary amide hypervalent iodine reagent Hofmann rearrangement carboxylation.Name: Picolinamide.
A novel transformation of primary amides RC(O)NH2 (R = Ph, thiophen-2-yl, Bu, cyclopropyl, etc.) to secondary amides RNHC(O)R1 (R1 = methyltrifluoromethyl, Et, Ph, etc.) promoted by hypervalent iodine reagents Ph(I)(OC(O)R1)2 was developed. The hypervalent iodine reagent-mediated Hofmann-type rearrangement generated an isocyanate intermediate, which was subsequently trapped by an in situ generated carboxylic acid from the hypervalent iodine reagent to provide the corresponding secondary amides. This method provided a facile and efficient route for the synthesis of secondary amides from primary amides and also revealed novel reactivities of hypervalent iodine reagents.
After consulting a lot of data, we found that this compound(1452-77-3)Name: Picolinamide can be used in many types of reactions. And in most cases, this compound has more advantages.
