He, Tian-Jun; Zhu, Shijun; Lu, Xiao-Wei; Wu, Yikang; Li, Yan published an article in 2015, the title of the article was Absolute Configurations of Melanoxadin, MR-93A, Melanoxazal, and MR-93B.Computed Properties of 3976-69-0 And the article contains the following content:
Fungal metabolites melanoxadin, MR-93A, melanoxazal and MR-93B were synthesized with the key stereogenic centers derived from com. available chiral building blocks. The optically active synthetic products with well-defined absolute configurations provided authentic samples for the stereoisomers of these oxazole-containing natural products and thus allowed for unambiguous assignments of their relative and absolute configurations. The large discrepancies in the optical rotations between the natural and the pure synthetic samples are discussed. Some errors in the previously reported NMR signal assignments are also corrected The synthesis of the target compounds was achieved using (2S)-2-hydroxypropanoic acid Et ester and (3S)-3-hydroxybutanoic acid, (3R)-3-hydroxybutanoic acid as chiral source materials. The experimental process involved the reaction of (R)-Methyl 3-hydroxybutanoate(cas: 3976-69-0).Computed Properties of 3976-69-0
