    • The water molecule found in dry cerium(III) chloride seems to have no effect, since the material was highly efficient without a large excess of reducing agent. cf. Evans, W. J.; Feldaman, J. D.; Ziller, J. W. J. Am. Chem. Soc. 1996, 118, 4581.

    • 1H NMR spectrum was measured after warming to -78°C, it was referenced to residual tetrahydrofuran (δ 3.58 ppm, δ 1.73 ppm), and a broad new peak did not appear.

    • Descriptors R*,S* indicate that diastereomeric compounds are obtained as racemates. We prefer this terminology to avoid the ambiguities that could arise from syn-anti descriptors.
