Nickel-Catalyzed 1,4-Addition of Trialkylboranes to α,β-Unsaturated Esters: Dramatic Enhancement by Addition of Methanol
摘要:
[GRAPHICS]Nickel catalyst systems for 1,4-addition of trialkylboranes to alpha,beta-unsaturated esters have been developed. Addition of methanol was found to be essential for the alkylation reaction with 9-alkyl-9-BBNs.
