The allylation reactions of aldehydes and ketones were carried out in 25%-98% (or 29%-96%) yield with La/SnCl2/H2O under ultrasound irradiation (or stirring) at rt for 1h (or 4h). The main advantage of the present procedure is the hi

Several phenylbutenoid dimer (PBD) analogs were synthesized and evaluated for their inhibitory activities against nitric oxide (NO) production and TNF-α release. The PBD analogs were synthesized via Diels - Alder and subsequent Schlosser reactions as key steps. Among the tested compounds, two analogs (8c, 8f) exhibited much stronger inhibitory activity against LPS-stimulated NO production and TNF-α release in RAW 264.7 cells than that of wogonin.

Straightforward and facile synthesis of a bioactive component A from Zingiber cassumunarRoxb. is described. The phenylbutenoid dimer A was reported to possess anti-inflammatory and cytotoxic activities. The optically active cyclohexene ring fragment was o
Diastereoselective allylation and crotylation reactions of aldehydes with potassium allyl- and crotyltrifluoroborates under Lewis acid catalysis
Batey, Robert A.,Thadani, Avinash N.,Smil, David V.,Lough, Alan J.
, p. 990 - 998 (2007/10/03)
Potassium allyl- and crotyltrifluoroborates react with aldehydes in a process catalyzed by a variety of Lewis acids, to give the corresponding homoallylic alcohols. Of the Lewis acids examined, BF3·OEt2, used either stoichiometrically or catalytically, was found to most efficiently catalyze this reaction. The air and moisture stable potassium organotrifluoroborate salts react with a variety of alkyl, α- or β- substituted alkyl, and aryl aldehydes, and lead to the adducts in high yield and with high diastereoselectivity.
Potassium allyl- and crotyltrifluoroborates: Stable and efficient agents for allylation and crotylation
Batey, Robert A.,Thadani, Avinash N.,Smil, David V.
, p. 4289 - 4292 (2007/10/03)
Potassium allyl- and crotyltrifluoroborates react rapidly with aldehydes in the presence of BF3 · Et2O. These salts are stable to air and moisture, and lead to adducts in high yield and with high diastereoselectivity. The stereochemistry of the crotylated products is consistent with the reaction via allylboron difluoride and a Zimmerman-Traxler like transition state.
A Grignard-Type Addition of Allyl Unit to Aldehydes by Using Bismuth and Bismuth Salt

, p. 1738 - 1747 (2007/10/02)
In the presence of metallic bismuth, bismuth(III) chloride-metallic zinc, or bismuth(III) chloride-metallic iron, allylic halides have been found to react with aldehydes under mild conditions to give the corresponding homoallylic alcohols in high yields with high chemo-, regio-, and stereoselectivity.Allylic halides have been also found to react with aldehydes at room temperature in tetrahydrofuran-water by using bismuth(III) chloride-metallic aluminium to afford the expected homoallylic alcohols in high yields.

Wada, Makoto,Ohki, Hidenori,Akiba, Kin-ya
, p. 4771 - 4774 (2007/10/02)
In the presence of bismuth(III) chloride-metallic zinc or bismuth(III) chloride-metallic iron, allylic halides were found to react with aldehydes under mild conditions to give the corresponding homoallylic alcohols in high yields with high chemoselectivity.
