Scheme 4. Diastereoselective, One-Pot Tandem Triborylation–Conjugate Addition–Alkylationa.

Scheme 4

aIsolated yields. See SI for experimental details. Diastereomeric ratios (dr) determined by gas chromatography of crude reaction mixtures and confirmed by 1H NMR spectroscopy of isolated products. bDiastereomers assigned by analogy to that of 16. cNMR yield; 22% isolated yield.
