Lu, Jun; Ji, Shun-Jun; Teo, Yong-Chua; Loh, Teck-Peng published an article on January 6 ,2005. The article was titled 《Highly Enantioselective Allylation of Aldehydes Catalyzed by Indium(III)-PYBOX Complex》, and you may find the article in Organic Letters.Safety of 2,6-Bis((R)-4-isopropyl-5,5-diphenyl-4,5-dihydrooxazol-2-yl)pyridine The information in the text is summarized as follows:
A chiral indium(III)-PYBOX complex prepared from indium triflate and chiral PYBOX has been discovered to effect high enantioselectivities in the addition of allyltributylstannane to aldehydes. The allylation of a variety of aromatic, α,β-unsaturated, and aliphatic aldehydes resulted in good yields and high enantioselectivities (up to 94% ee). After reading the article, we found that the author used 2,6-Bis((R)-4-isopropyl-5,5-diphenyl-4,5-dihydrooxazol-2-yl)pyridine(cas: 828918-24-7Safety of 2,6-Bis((R)-4-isopropyl-5,5-diphenyl-4,5-dihydrooxazol-2-yl)pyridine)
2,6-Bis((R)-4-isopropyl-5,5-diphenyl-4,5-dihydrooxazol-2-yl)pyridine(cas: 828918-24-7) belongs to pyridine derivatives. Several pyridine derivatives play important roles in biological systems. While its biosynthesis is not fully understood, nicotinic acid (vitamin B3) occurs in some bacteria, fungi, and mammals. Safety of 2,6-Bis((R)-4-isopropyl-5,5-diphenyl-4,5-dihydrooxazol-2-yl)pyridine
