, (2020/01/28)
All four chiral pestalotin diastereomers were synthesized in a straightforward and divergent manner from common (R)-glycidol. Catalytic asymmetric Mukaiyama aldol reactions of readily-available bis(TMSO)diene (Chan’s diene) with (S)-2-benzyloxyhexanal der

, p. 693 - 700 (2007/10/02)
Aldol condensation of the bistrimethylsilyl enol ether of methyl acetoacetate, compound 2, with 2-benzyloxyhexanal 3c affords highly selectively (99:1) the syn-aldol adduct 4c in the presence of titanium tetrachloride.The stereocontrolled synthesis of (-)-pestalotin 7 has been achieved.

Titanium tetrachloride-mediated aldol condensation of the bistrimethylsilyl enol ether of methyl acetoacetate (1) with 2-benzyloxyhexanal (3) gives highly selectively (99:1) the syn aldol adduct (5); the stereocontrolled synthesis of (-)-pestalotin (9) ha
ON THE STERIC COURSE OF THE ADDITION OF SOME ORGANOMETALLIC REAGENTS TO (R)-2,3-ISOPROPYLIDENE GLYCERALDEHYDE. SYNTHESIS OF OPTICALLY ACTIVE α-BENZYLOXY ALDEHYDES, ALCOHOLS, CARBOXYLIC ACIDS AND 1,2-DIOLS.
Mulzer, Johann,Angermann, Alfred
, p. 2843 - 2846 (2007/10/02)
Organo-titanium and organo-zinc reagents were added stereoselectively to (R)-2,3-isopropylidene glyceraldehyde (1) to give the alcohols 2/3, which were converted into the optically active derivatives 4-11.
AN ASYMMETRIC SYNTHESIS OF α-BENZYLOXY ALDEHYDES HAVING A CHIRAL TERTIARY CENTER - AN APPLICATION TO THE ASYMMETRIC SYNTHESIS OF exo-(+)-BREVICOMIN -
Asami, Masatoshi,Mukaiyama, Teruaki
, p. 93 - 96 (2007/10/02)
α-benzyloxy aldehydes having a chiral tertiary center at α-carbon atom are synthesized in high enantiomeric excess by successive treatment of 2-methoxycarbonyl-3-phenyl-1,3-diazabicyclooctane with diisobutylaluminum hydride (DIBAL-H) and Grignard reagents.The asymmetric reaction is applied to the total synthesis of exo-(+)-brevicomin.
