Abstract
| - The DIBAL reduction of 2-phenylethyl 3,3,3-trifluoro-2-methylpropionate 2 at −78 °C afforded the aluminum acetal3, and this intermediate, on worming up to 0 °C, was foundto slowly decompose into the corresponding aldehyde 4,which smoothly reacted with appropriate nucleophiles in aone-pot manner in good to excellent yields with up to 93%diastereoselectivity.
