合成路线1
该中间体在本合成路线中的序号：(XLIX)Acid-catalyzed deprotection of the N-Boc and O-silyl groups of (XLV) leads to (XLVI). The primary hydroxyl group of (XLVI) is then tosylated to afford (XLVII). Subsequent esterification of the remaining tertiary hydroxyl with trifluoroacetic anhydride and pyridine yields trifluoroacetate (XLVIII). Chlorination of the indole nucleus of (XLVIII) with t-butyl hypochlorite furnishes the chloroindolenine (XLIX). Thisi is then coupled to vindoline (XXIII) in the presence of trifluoroacetic acid to form the bis-indole adduct (L) (8,9).
