A new convenient method for the asymmetric transfer allylation of aromatic aldehydes was developed. The reaction gave the best results using a chiral allyl donor molecule derived from (-)-menthone in the presence of heteropoly acids supported on silica gel under solvent-free conditions, and the desired homoallylic alcohol derivatives were obtained in good yields with good to high enantioselectivity.

A series of chiral Lewis bases, phosphine oxide ferrocenyl aziridinyl methanol 1-4, phosphinyl aziridinyl phosphonates 5 and 6, and phosphine oxide aziridinyl phosphonates 7 and 8 were screened for allylsilane additions to aldehydes. Among the Lewis bases

An efficient asymmetric synthesis of homoallylic alcohols is described by the allylation of carbonyl compounds using organocatalysts as chiral directors in the presence of tin metal. The effect of chiral environment is also studied on the allylation reactions. This method allows us to obtain two different enantiomers of homoallylic alcohol in the presence of the corresponding chiral compound. The protocol is applied to various aldehydes to obtain high yields and excellent enantioselectivities for the corresponding homoallylic alcohols.

Chiral 2-methylsulfinyl benzaldehyde proved to be a valuable starting material for a convenient approach towards a variety of imino- and amino-sulfoxides. The catalytic properties of these new ligands, as potential activators of allyl trichlorosilane, hav
Asymmetrie allylation of aldehydes catalyzed by simple dual small organic molecules: L-proline and L-prolinol

scheme or table, p. 1013 - 1015 (2011/01/06)
A novel and simple methodology for the asymmetric allylation of aldehydes was reported. Double small organic molecules such as L-proline and L-prolinol were first employed for providing a chiral environment so as to afford chiral homoallylic alcohols in high yields and moderate enantioselectivities in our protocol.
