Sustainable, efficient, selective: A three-component, single-vessel Cu-catalyzed method for chemo-, diastereo-, and enantioselective conversion of B2(pin)2, monosubstituted allenes, and aldehydes or ketones to 2-B(pin)-substituted homoallylic alkoxides is described. Subsequent functionalization delivers valuable products in up to >98:2 d.r. and 97:3 e.r. (see scheme). Copyright

Giving it a boost: A mechanistic study of the enantioselective asymmetric titled reaction with allyldiisopropoxyborane catalyzed by chiral biphenols revealed a key ligand exchange process which liberates isopropyl alcohol. The addition of iPrOH to the rea
Asymmetric allylboration of ketones catalyzed by chiral diols

, p. 12660 - 12661 (2008/02/05)
Chiral BINOL-derived diols catalyze the enantioselective asymmetric allylboration of ketones. The reaction requires 15 mol % of 3,3′-Br2-BINOL as the catalyst and allyldiisopropoxyborane as the nucleophile. The reaction products are obtained in
Silver-catalyzed asymmetric Sakurai-Hosomi allylation of ketones
Wadamoto, Manabu,Yamamoto, Hisashi
, p. 14556 - 14557 (2007/10/03)
The complex of AgF and (R)-DIFLUORPHOS has been shown to be an effective catalyst for the asymmetric Sakurai-Hosomi allylation of simple ketones. A significaant improvement of the reactivity was observed by using THF as the solvent. The catalyst turnover

Wada, Reiko,Oisaki, Kounosuke,Kanai, Motomu,Shibasaki, Masakatsu
, p. 8910 - 8911 (2007/10/03)
The first example of catalytic enantioselective allylboration and crotylboration of simple ketones is described. High enantioselectivity (up to 93% ee) was obtained using 3 mol % CuF-iPr-DuPHOS as a chiral catalyst and 4.5 mol % La(Oi/sup
