In an article, author is Wang, Qiang, once mentioned the application of 5505-63-5, Name is (2S,3R,4S,5R)-2-Amino-3,4,5,6-tetrahydroxyhexanal hydrochloride, molecular formula is C6H14ClNO5, molecular weight is 215.6321, MDL number is MFCD09880213, category is chiral-catalyst. Now introduce a scientific discovery about this category, Category: chiral-catalyst.
A rhodium(III)-catalyzed enantioselective C-H activation/annulation process is disclosed. With a catalyst derived from a chiral CpRh(III) complex and a chiral acid, the direct annulation reactions between 1-aryl isoquinoline derivatives and alkynes take place smoothly to afford a series of chiral azoniahelicenes in excellent yields and enantioselectivity (up to 99% yield and 96% ee). Mechanistic studies suggest that C-H bond cleavage may be the turnover-limiting step.
