Chen, Caiyou published the artcileA new ferrocenyl bisphosphorus ligand for the asymmetric hydrogenation of ¦Á-methylene-¦Ã-ketocarboxylic acids, Product Details of C11H10O3, the publication is Chemical Communications (Cambridge, United Kingdom) (2017), 53(70), 9785-9788, database is CAplus and MEDLINE.
New diphosphine-amine chiral ligand tBu-Wudaphos I was prepared and examined for chiral induction in rhodium-catalyzed asym. hydrogenation of ¦Á-methylene-¦Ã-ketocarboxylic acids, yielding ¦Á-methyl-¦Ã-ketocarboxylates with more than 98% ee and quant. conversion. Upon incorporation of a noncovalent ion pair interaction, a new chiral ferrocenyl bisphosphorus ligand t-Bu-Wudaphos was developed. t-Bu-Wudaphos can be easily synthesized with very high diastereoselectivity as a highly air stable solid. The new ligand exhibited excellent reactivities and enantioselectivities in the asym. hydrogenation of ¦Á-methylene-¦Ã-keto-carboxylic acids via an ion pair noncovalent interaction (up to >99% conversion, >99% ee).
Chemical Communications (Cambridge, United Kingdom) published new progress about 15732-75-9. 15732-75-9 belongs to catalysis-chemistry, auxiliary class Alkenyl,Carboxylic acid,Benzene,Ketone, name is 2-Methylene-4-oxo-4-phenylbutanoic acid, and the molecular formula is C11H10O3, Product Details of C11H10O3.
