Tan, Nichole P. H.; Donner, Christopher D. published an article about the compound: (S)-2-Bromosuccinic acid( cas:20859-23-8,SMILESS:O=C(O)[C@@H](Br)CC(O)=O ).Recommanded Product: (S)-2-Bromosuccinic acid. Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:20859-23-8) through the article.
The first total synthesis of (S)-semiviriditoxin (I) is described. The approach utilizes a tandem Michael-Dieckmann reaction between an ortho-toluate and dihydropyran-2-one to construct the naphthopyranone core, the dihydropyran-2-one being prepared from (R)-1,2-epoxy-4-butanol. Spectroscopic comparison of synthetic I with (R)-semivioxanthin (II), prepared in four steps from (R)-propylene oxide, confirmed the (S)-stereochem. of natural semiviriditoxin from Paecilomyces variotii.
Although many compounds look similar to this compound(20859-23-8)Recommanded Product: (S)-2-Bromosuccinic acid, numerous studies have shown that this compound(SMILES:O=C(O)[C@@H](Br)CC(O)=O), has unique advantages. If you want to know more about similar compounds, you can read my other articles.
