実験手順

tert-Butyl (R)-2-(8-(tert-butoxycarbonyloxy)-2-oxo-1,2-dihydroquinolin-5-yl)-2-(tert-butyldimethylsilyloxy)ethyl((R)-1-(3-(hydroxymethyl)phenyl)propan-2-yl)carbamate (Example 276, step g) (0.609 g) was dissolved in dichloromethane (30 mL), treated with manganese (IV) oxide (0.791 g) and the resulting suspension stirred at room temperature over a weekend. More manganese (IV) oxide (0.801 g) was added and the suspension was stirred for a further 4 hours. The mixture was filtered through diatomaceous earth, washing the residue well with DCM, and the combined filtrate and washings were concentrated in vacuo to afford the subtitled compound. Yield 0.521 g. Material used immediately in the next step.
