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 A modular approach to marine macrolide construction. 2. Concise stereocontrolled synthesis of the C17-C28 (CD) spiroacetal component, published in 1997-07-21, which mentions a compound: 58081-05-3, mainly applied to altohyrtin A CD spiroacetal preparation; aldol condensation stereoselective, Recommanded Product: 58081-05-3.
The CD spiroacetal ring system (I) of altohyrtin A, which houses one-fifth of the stereogenic centers resident in the macrolide, has been synthesized through a combination of aldol condensations having different stereocontrol elements.
After consulting a lot of data, we found that this compound(58081-05-3)Recommanded Product: 58081-05-3 can be used in many types of reactions. And in most cases, this compound has more advantages.
