Stereoselective Synthesis of Vinylcyclopropanes via Palladium-Catalyzed Reactions
Baeckvall, J. E.,Vagberg, J. O.,Zercher, C.,Genet, J. P.,Denis, A.
, p. 5430 - 5435 (1987)
Vinylcyclopropanes were synthesized in a stereocontrolled manner from 1-acetoxy-4-chloro-2-alkenes.A stereospecific palladium-catalyzed substitution of the chloro group by dimethyl malonate anion and subsequent palladium-catalyzed cyclization afforded the

As unusual substrates for the Tsuji-Trost allylation reaction, allylic fluorides are responsive to palladiumcatalyzed substitution. Their activity towards this reaction fits in the series OCO2Me>OBz? F? OAc. The classic stereoretention mechanis

Asymmetric induction in the allylic alkylation of cycloalkenediol diacetates was performed using a chiral alkylphosphine ligand bearing a carboxyl group, 3-(diphenylphosphino)butanoic acid. An increase in enantiomeric excess of the monoalkylated products of cis-cycloalkenediol diacetates was observed through a sequential asymmetric allylic alkylation- kinetic resolution process.

Enzyme and palladium catalysis as a powerful combination in asymmetric transformations of meso-2-alkene-1,4-diol derivatives. Application to enantiodivergent synthesis of (R)- and (S)-(2,4-cycloalkadienyl)acetic acids
Backvall,Gatti,Schink
, p. 343 - 348 (2007/10/02)
Enzymatic hydrolysis of meso-diacetates cis-1,4-diacetoxy-2-cyclo-hexene (4a) and cis-1,4-diacetoxy-2-cycloheptene (4b) was used to prepare enantiomerically pure (> 98% ee) 4-acetoxy-2-cyclohexenol (5a) and 4-acetoxy-2-cycloheptenol (5b), respectively. Th
STEREOSPECIFIC PALLADIUM-CATALYZED 1,4-ACETOXYCHLORINATION OF 1,3-DIENES
Baeckvall, Jan-E.,Nordberg, Ruth E.,Nystroem, Jan-E.
, p. 1617 - 1620 (2007/10/02)
Palladium-catalyzed oxidation of 1,3-dienes in acetic acid in the presence of LiCl and LiOAc produces 1-acetoxy-4-chloro-2-alkenes in high selectivity.The 1,4-adducts were stereo- and regioselectively functionalized.
