    • The tethered aminohydroxylation was carried out in small scale and it has been previously reported that under these conditions the yields vary unpredictably from 4% to 40%. See:

    • 2S with good yield and selectivity (90%, cis:trans, 91:9). Unfortunately, selective protection to generate 18 was not efficient. These results will be described in detail in due time.

    • We first studied the process for the tosyloxy derivative, but the yields were moderate and the starting material was not recovered, under these conditions. In contrast, the mesitylsulfonyloxy derivative was more stable and gave higher yields in the aminohydroxylation step.
