Access to 6-hydroxy indolizines and related imidazo[1,5-a]pyridines through the SN2 substitution/condensation/tautomerization cascade process was written by Duan, Guiyun;Liu, Hao;Zhang, Liqing;Yuan, Chunhao;Li, Yongchao;Ge, Yanqing. And the article was included in RSC Advances in 2021.Quality Control of Ethyl 4-chloro-3-oxobutanoate The following contents are mentioned in the article:
A simple and efficient cascade reaction was developed for the construction of hydroxy substituted indolizines I [R1 = CHO, COMe, I, etc.; R2 = H, COOMe, Cl, etc.] and imidazopyridines II [R3 = H, Me; R4 = Me, Et] from pyrrole-2-carbaldehydes and com. available 4-halogenated acetoacetic esters. Their optical properties were also evaluated. This study involved multiple reactions and reactants, such as Ethyl 4-chloro-3-oxobutanoate (cas: 638-07-3Quality Control of Ethyl 4-chloro-3-oxobutanoate).
Ethyl 4-chloro-3-oxobutanoate (cas: 638-07-3) belongs to organic chlorides. An organic chloride is an organic compound containing at least one covalently bonded atom of chlorine. Their wide structural variety and divergent chemical properties lead to a broad range of names and applications. Alkyl chlorides are versatile building blocks in organic chemistry. While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available.Quality Control of Ethyl 4-chloro-3-oxobutanoate
