Meyers, A. I.; Yamamoto, Yukio published the article 《Stereoselectivity in the aldol reaction. The use of chiral and achiral oxazolines as their boron azaenolates》. Keywords: aldol stereoselectivity; oxazoline boron enolate aldehyde; ester hydroxy stereoselectivity.They researched the compound: 2-Ethylbenzo[d]oxazole( cas:6797-13-3 ).Related Products of 6797-13-3. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:6797-13-3) here.
Chiral oxazolines, as their B enolates derived from various B triflates, react with aldehydes to give erythro-selectivity (>97%) with enantiomeric purities of 50-60%. Achiral oxazolines as their B enolates derived from diisopinocamphenylborane give, on reaction with aldehydes, β-hydroxy esters with high threo-selectivity (>90%) in 77-85% enantiomeric excess. A variety of structurally different oxazolines were also studied and many show high erythro-selectivity.
This literature about this compound(6797-13-3)Related Products of 6797-13-3has given us a lot of inspiration, and I hope that the research on this compound(2-Ethylbenzo[d]oxazole) can be further advanced. Maybe we can get more compounds in a similar way.
