    • note
    • Preferential formation of (2R,4R)-9b to (2S,4S)-9b might be caused by a dehydrogenative coupling of 8b with diphenylsilane. Based on the asymetric hydrosilylation of 3c (Table 4), the remaining carbonyl group of the resulting silyl enol ether, which is an α,β-unsaturated ketone, would be reduced with R-selectivity by diphenylsilane and (R,R)-(S,S)-alkylTRAP-rhodium caltalyst. (equation presented)
