Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Research Support, Non-U.S. Gov’t, Organic & Biomolecular Chemistry called Thiosquaramide-catalysed asymmetric double Michael addition of 2-(3H)-furanones to nitroolefines, Author is Yang, Mengchen; Chen, Chen; Yi, Xing; Li, Yuan; Wu, Xiaoqin; Li, Qingshan; Ban, Shurong, which mentions a compound: 591-12-8, SMILESS is O=C1OC(C)=CC1, Molecular C5H6O2, HPLC of Formula: 591-12-8.
New chiral thiosquaramides and their applications in catalytic asym. double addition of 5-methyl-2(3H)-furanones to nitroolefins were described. Enantiomerically enriched 2,4,4-trisubstituted butenolides bearing a quaternary stereogenic center could be smoothly constructed with high diastereoselectivities (up to >99 : 1 dr) and excellent enantioselectivities (up to 95% ee) under mild conditions.
From this literature《Thiosquaramide-catalysed asymmetric double Michael addition of 2-(3H)-furanones to nitroolefines》,we know some information about this compound(591-12-8)HPLC of Formula: 591-12-8, but this is not all information, there are many literatures related to this compound(591-12-8).
