A highly chemo- and stereo-selective cleavage of acetals derived from (-)(2R,4R)-2,4-pentanediol with organoaluminum and organotitanium reagents has been demonstrated. The reactions proceed under mild conditions with excellent yields and high chemoselectivities to give, after removal of the auxiliary, chiral alcohols of high enantiomeric purities.
ASYMMETRIC SYNTHESIS via CHIRAL ACETAL TEMPLATES. 8. REACTIONS WITH ORGANOMETALLIC REAGENTS
Lindell, Stephen D.,Elliott, John D.,Johnson, William S.
, p. 3947 - 3950 (2007/10/02)
The titanium tetrachloride catalyzed coupling of organometallic reagents with chiral acetals 1 is shown to provide a convenient route for the preparation of a variety of chiral alcohols 4 of high optical purity.
