Enantioselective synthesis of tarchonanthuslactone using proline-catalyzed asymmetric α-aminooxylation
George, Shyla,Sudalai, Arumugam
, p. 975 - 981 (2008/02/03)
A practical enantioselective synthesis of tarchonanthuslactone 1, an important natural product with a polyol unit, is described. The sequence of synthetic reactions involves proline-catalyzed α-aminooxylation and iodine-induced electrophilic cyclization as the chiral inducing steps.
An efficient organocatalytic route to the atorvastatin side-chain
George, Shyla,Sudalai, Arumugam
, p. 8544 - 8546 (2008/09/17)
An organocatalytic route to the synthesis of the atorvastatin side-chain, a building block present in the statin family, is described using l-proline-catalyzed α-aminooxylation of an aldehyde. The method also employs an iodine-induced intramolecular electrophilic cyclization of a carbonate to produce the iodocarbonate in a highly diastereoselective manner.
Synthesis of (+)-methyl (R,E)-6-benzyloxy-4-hydroxy-2-hexenoate and its mesylate derivative
De March,Figueredo,Font,Monsalvatje
, p. 331 - 342 (2007/10/02)
Methyl (E)-6-benzyloxy-4-hydroxy-2-hexenoate is prepared in both racemic and enantiopure form through reaction between (2-benzyloxy)ethyloxirane and the dianion of phenylselenoacetic acid followed by esterification with diazomethane, oxidation to the selenoxide and subsequent pyrolysis in 72% overall yield.
L-(S)-ERYTHRULOSE : THE SYNTHESYS OF (R)-1,2,4-BUTANETRIOL AND OF SOME RELATED C4 CHIRONS.
Eycken, E. Van der,Wilde, H. De,Deprez, L.,Vandewalle, M.
, p. 4759 - 4760 (2007/10/02)
L-(S)-Erythrulose can easily be transformed into (R)-1,2,4-butanetriol and related C4 chiral building blocks.A formal synthesis of (-)-GABOB is presented.Also the formation of 3-methylene-1,2,4-butanetriol derivatives is described.
