Divergent asymmetric total synthesis of all four pestalotin diastereomers from (R)-glycidol

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

High Diastereoselection in the Aldol Reaction of the Bistrimethylsilyl Enol Ether of Methyl Acetoacetate with 2-Benzyloxyhexanal: Synthesis of (-)-Pestalotin

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.

Highly Diastereoselective Titanium Tetrachloride-mediated Aldol Condensation of the Bistrimethylsilyl Enol Ether of Acetoacetic Ester with 2-Benzyloxyhexanal. A Synthesis of (-)-Pestalotin

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

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 -

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.
