Efficient 1,8- and 1,9-asymmetric inductions in the Grignard reaction of δ- and ɛ-keto esters of 1,1′-binaphthalen-2-ols with an oligoether tether as the 2′-substituent: application to the synthesis of (−)-malyngolide

A Pd-catalyzed enantioselective γ-selective arylation of β, γ-unsaturated butenolides is reported. The P-chiral phosphine ligand-AntPhos is essential for the observed high γ-selectivity, excellent enantioselectivity and good yields.
A CuH-catalyzed enantioselective and regiodivergent allyl addition to ketones with allenylsilanes has been developed. Various tertiary homoallylic alcohols bearing an alkenyl silane or an allyl silane group were synthesized with high regioselectivities and excellent enantioselectivities.

A copper(I)-catalyzed asymmetric allylation of ketones with 2-aza-1,4-dienes (N-allyl-1,1-diphenylmethanimines) is disclosed, which affords a series of functionalized homoallyl tertiary alcohols in high to excellent enantioselectivity.
