Palladium-catalyzed allylation of imines with allyl alcohols.

Organic letters

Shimizu M, Kimura M, Watanabe T, Tamaru Y.
PMID: 15704913
Org Lett. 2005 Feb 17;7(4):637-40. doi: 10.1021/ol047609f.

A catalytic system, Pd(OAc)2 (10 mol %)-P(n-Bu)3 (20 mol %)-Et3B (360 mol %), promotes allylic alcohols to undergo the allylation of anisidine-imines of aromatic and aliphatic aldehydes and furnishes homoallylamines in good to moderate yields. The reaction shows unique...

Nickel-catalyzed addition of dimethylzinc to aldehydes across alkynes and 1,3-butadiene: an efficient four-component connection reaction.

Journal of the American Chemical Society

Kimura M, Ezoe A, Mori M, Tamaru Y.
PMID: 15631469
J Am Chem Soc. 2005 Jan 12;127(1):201-9. doi: 10.1021/ja0469030.

In the presence of 10 mol % of Ni(acac)(2), four components comprising Me(2)Zn, alkynes, 1,3-butadiene, and carbonyl compounds combine in this order in 1:1:1:1 ratio to furnish (3E,6Z)-octadien-1-ols 1 in good yields. Similarly, the coupling reaction of Me(2)Zn, 1,omega-dienynes...
