该中间体在本合成路线中的序号：(XXXVIII)

The cleavage of the 4-methoxybenzyl group of (XXXIII) with DDQ in dichloromethane/water gives the secondary alcohol (XXXIV), which is oxidized with pyridinium dichromate (PDC) in dichloromethane yielding the corresponding ketone (XXXV). The cyclization of (XXXV) with AcOH affords the tetracyclic compound (XXXVI), which is silylated at the carbinol group with Tes-OTf and lutidine giving the silyl ether (XXXVII). The oxidation of (XXXVII) with DMP in refluxing benzene affords the carbinol (XXXVIII), which is selectively desilylated and cyclized with TFA in dichloromethane/water giving the pentacyclic compound (XXXIX). The oxidation of the hydroxymethyl group of (XXXIX) with DMP in dichloromethane yields corresponding aldehyde (XL), which is silylated at the remaining OH group with Tbdms-OTf and lutidine in dichloromethane to afford the silyl ether (XLI). The oxidation of the aldehyde group of (XLI) with NaClO2 in tert-butanol/water gives the carboxylic acid (XLII).

该中间体在本合成路线中的序号：(XLII)

The selective hydrolysis of (XXXV) with aqueous AcOH gives the alpha hydroxy ketone (XXXVI), which is silylated at the OH group with TBDMS-OTf and lutidine in dichloromethane yielding the silyl ether (XXXVII). The cleavage of the 4-methoxybenzyl group of (XXXVII) with DDQ in CH2Cl2/H2O gives the secondary alcohol (XXXVIII), which is oxidized with pyridinium dichromate (PDC) in dichloromethane yielding the corresponding ketone (XXXIX). The cyclization of (XXXIX) with AcOH affords the tetracyclic compound (XL), which is silylated at the carbinol group with TES-OTf and lutidine giving the silyl ether (XLI). The oxidation of (XLI) with DMP in refluxing benzene affords the carbinol (XLII), which is selectively desilylated and cyclized with TFA in CH2Cl2/H2O giving the pentacyclic compound (XLIII). The oxidation of the hydroxymethyl group of (XLIII) with DMP in CH2Cl2 yields corresponding aldehyde (XLIV).
