In an article, author is Wei, Shiqiang, once mentioned the application of 141-22-0, Safety of (R,Z)-12-Hydroxyoctadec-9-enoic acid, Name is (R,Z)-12-Hydroxyoctadec-9-enoic acid, molecular formula is C18H34O3, molecular weight is 298.46, MDL number is MFCD00084840, category is chiral-catalyst. Now introduce a scientific discovery about this category.
A novel tartrate-derived guanidine accessed by a modular approach was identified to be an efficient catalyst for the Michael addition of 3-aminooxindoles to nitroolefins. A range of quaternary 3-aminooxindoles bearing adjacent quaternary-tertiary stereocenters were obtained in good to excellent yields (up to 95%) with good to excellent diastereo- and enantioselectivities (up to >20:1 dr and 98% ee).
