On September 1, 2017, Luo, Shipeng; Zhang, Xiao; Zheng, Yu; Harms, Klaus; Zhang, Lilu; Meggers, Eric published an article.Recommanded Product: (Trimethoxymethyl)benzene The title of the article was Enantioselective Alkynylation of Aromatic Aldehydes Catalyzed by a Sterically Highly Demanding Chiral-at-Rhodium Lewis Acid. And the article contained the following:
The enantioselective catalytic alkynylation of aromatic aldehydes is reported using a sterically highly hindered bis-cyclometalated rhodium-based Lewis acid catalyst featuring the octahedral metal as the only stereogenic center. Yields of 58-98% with 79-98% enantiomeric excess were achieved using 1-2 mol % of catalyst. This work complements previous work from the authors’ laboratory on the enantioselective alkynylation of 2-trifluoroacetyl imidazoles and trifluoromethyl ketones using catalysts with octahedral metal-centered chirality. The experimental process involved the reaction of (Trimethoxymethyl)benzene(cas: 707-07-3).Recommanded Product: (Trimethoxymethyl)benzene
The Article related to biscyclometalated rhodium lewis acid catalyst preparation mol crystal structure, arylaldehyde terminal alkyne enantioselective alkynylation biscyclometalated rhodium lewis acid, chiral diaryl propargylic alc preparation and other aspects.Recommanded Product: (Trimethoxymethyl)benzene
