Sakurai, Yohji published the artcile< Tandem Sonogashira-Hagihara coupling/cycloisomerization reactions of ethynylboronic acid mida ester to afford 2-heterocyclic boronic acid mida esters: a concise route to benzofurans, indoles, furopyridines and pyrrolopyridines>, COA of Formula: C5H4INO, the main research area is Sonogashira Hagihara coupling cycloisomerization ethynylboronic mida ester; heterocyclic boronic mida preparation conversion benzofuran indole furopyridine pyrrolopyridine.
A one-pot process that provides direct access to 2-heterocyclic MIDA (N-methyliminodiacetic acid) boronates has been developed. The reaction of 2-iodophenols or 2-iodoanilines with ethynylboronic acid MIDA ester readily afforded 2-substituted heterocyclic compounds Amidine and phosphazene bases, especially TMG (1,1,3,3-tetramethylguanidine) assumed an important role in the tandem Sonogashira-Hagihara coupling/cycloisomerization reactions.
Heterocycles published new progress about Benzofurans Role: SPN (Synthetic Preparation), PREP (Preparation). 188057-20-7 belongs to class iodides-buliding-blocks, and the molecular formula is C5H4INO, COA of Formula: C5H4INO.
