Abstract :
α-Lithiated 1-[(2-methoxyethoxy)methoxy]-2-(phenylsylfinyl)cyclopropane reacted smoothly with alkylating agents to afford the corresponding α-alkylated cyclopropylsulfoxides, which underwent the Pummerer-type reaction mediated ring-opening at low temperature (−78°C) by employing TFAA/Pri2NEt/CH2Cl2 to give mixtures of β-(phenylthio)-α,β- and γ,δ-unsaturated aldehydes.
