実験手順

A solution of (R)-3-((R)-2-(((9H-fluoren-9-yl)methoxy)carbonylamino)-3-tert-butoxy-3-oxopropyl thio)propane-1,2-diyl didodecanoate (11) in 40% TFA in DCM (0.3 M) was stirred at room temperature until complete deprotection of tert-butyl group (2 hr). The reaction mixture was diluted in MTBE, washed three times with 1M citric acid (adjusted to pH3), and once with 1:2 1N HCl/brine. The organic layer was dried over anhydrous Na2SO4 and concentrated en vacuo. The resulting waxy solid was used without further purification.
