Krysan, Damian J. published the artcile< A dramatic reversal of facial selectivity in the Sharpless asymmetric dihydroxylation of a sterically hindered 3-methylidene-benzofuran>, Name: (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is benzofuran asym dihydroxylation catalyst; dihydroquinine catalyst asym osmylation; dihydroquinidine catalyst asym osmylation; osmylation asym catalyst dihydroquinine dihydroquinidine.
Reversal of π-facial selectivity in the osmium-catalyzed asym. dihydroxylation (AD) of an exocyclic olefin I was reported. Switching from a phthalazine-linked ligand (DHQ2PHAL or DHQD2PHAL) to a pyrimidine-linked ligand (DHQ2PYR or DHQD2PYR) led to the opposite enantiomer using the same pseudo-enantiomer of the cinchona alkaloid.
Tetrahedron Letters published new progress about Dihydroxylation catalysts, stereoselective. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Name: (9Z,12Z)-Methyl octadeca-9,12-dienoate.
