In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Rh(III)-Catalyzed olefination to build diverse oxazole derivatives from functional alkynes, published in 2021, which mentions a compound: 92-71-7, mainly applied to oxazole preparation stereoselective; alkyne oxazole rhodium catalyst olefination, HPLC of Formula: 92-71-7.
A novel Rh(III)-catalyzed olefination reaction of oxazoles to generate diverse oxazole skeleton derivatives has been realized by directly using oxazole as the directing group. The reaction could tolerate many functional groups, affording complex oxazole derivatives with long chain alkenyls in moderate to good yields, which might find applications in the construction of diverse compounds
Compounds in my other articles are similar to this one(2,5-Diphenyloxazole)HPLC of Formula: 92-71-7, you can compare them to see their pros and cons in some ways,such as convenient, effective and so on.
