Warashina, Takuya; Matsuura, Daisuke; Sengoku, Tetsuya; Takahashi, Masaki; Yoda, Hidemi; Kimura, Yoshikazu published the artcile< Regioselective Formylation of Pyrrole-2-Carboxylate: Crystalline Vilsmeier Reagent vs Dichloromethyl Alkyl Ether>, SDS of cas: 7126-50-3, the main research area is regioselective formylation pyrrolecarboxylate; crystalline Vilsmeier reagent dichloromethyl alkyl ether preparation; formyl pyrrolecarboxylate preparation.
New preparations of crystalline Vilsmeier reagent (VR) and dichloromethyl Pr or Bu ether were developed. The methods are environmentally benign and applicable to large-scale synthesis. Formylations of 1H-pyrrole-2-carboxylates were achieved with these reagents, regioselectively affording the 4-formyl and 5-formyl derivatives in nearly quant. yields.
Organic Process Research & Development published new progress about Ethers Role: RCT (Reactant), SPN (Synthetic Preparation), RACT (Reactant or Reagent), PREP (Preparation) (dichloromethyl alkyl). 7126-50-3 belongs to class esters-buliding-blocks, and the molecular formula is C8H9NO3, SDS of cas: 7126-50-3.
