Asymmetric ortho-deprotonation of (η6-arene) chromium tricarbonyl complexes substituted with a chiral hydroxylamine

Add time:07/30/2019    Source:sciencedirect.com

The use of O-methyl-N-(α-methylbenzyl)hydroxylamine as a novel chiral auxiliary in asymmetric ortho-deprotonation of the (η6-arene) chromium tricarbonyl complexes is described. Upon quenching of the resultant ortho-lithiated complex with an electrophile, 1,2-disubstituted (η6-arene) chromium tricarbonyl complexes were obtained in good yield and excellent levels of diastereoselectivity.
