The article was titled ãAsymmetric total synthesis of phomarolã? and you may find the article in CCS Chemistry.Safety of Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate The information in the text is summarized as follows:
The first and asym. total synthesis of phomarol I, an uncommon C25 steroid, was described. The synthetically challenging benzocycloheptane motif, found in phomarol and some other naturally occurring mols., was synthesized efficiently using a very mild acid-promoted type I [5+2] cycloaddition, followed by regio- and chemoselective cleavage of the C-O bond and aromatization cascade. This work was the first example of using the hydrogen bonding between the hydroxy group and oxidopyrylium ylide to control the stereoselectivity of cycloadditions The highly functionalized tetrahydropyran ring of phomarol was produced efficiently based on our suggested biomimetic pathway.Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate(cas: 6381-59-5Safety of Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate) was used in this study.
Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate(cas: 6381-59-5) is a ferroelectric crystal with a high piezoelectric effect and electromechanical coupling coefficient. Safety of Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate It may be used as a constituent to prepare DNS (3,5- dinitrosalicylic acid) reagent and Fehling′s solution B, which are used in the determination of reducing sugar.
