Reaction Steps
This compound is obtained by the S-detritylation of 15 (2.75 mmol). The protocol used is the same as that described in example 1 for the synthesis of I-152. After the various treatments, a gum is collected, which gum is purified by flash chromatography on a silica gel column (eluent: CH2Cl2/ether 25%). I-208 is isolated in the form of a gum which, after trituration in hexane, provides a colorless powder (Yd=69%). Rf (CH2Cl2/ether, 5/5): 0.39. M.p.=125-127° C. [α]D20=−25.7° (c 1.05, CHCl3).
