Thiopyran route to polypropionates : simultaneous-two directional and enantiotopic group selective aldol reactions
The sequential aldol reactions of thiopyran derivatives 112 and 119 to rapidly generate hexapropionate building blocks in two carbon-carbon forming steps has been well studied within the Ward group. An extension of this strategy to generate non-racemic tetra- and hexapropionate fragments involved …

ALDOL COUPLINGS OF CHIRAL FRAGMENTS WITH KINETIC RESOLUTION: SCOPE AND LIMITATIONS
“The Thiopyran Route to Polypropionates” is a synthetic strategy that involves the stepwise aldol reactions of 6 and 7a to rapidly access stereochemically complex tetrapropionate 8 and hexapropionate synthons 72 or 73. Coupling racemic 7a with any of the four enantioenriched diastereomers 8 with …
