合成路线1
该中间体在本合成路线中的序号：(XLV)(XLIII) is silylated with TIPS-SO3CF3 to the protected ester (XLIV). The reduction of (XLIV) with diisobutylaluminum hydride yields the primary alcohol (XLV), which is oxidized with the complex pyridine - SO3 to the aldehyde (XLVI). The condensation of (XLVI) with the boron enolate of the oxazolidone (XLVII) affords the oxazolidone derivative (XLVIII), which is treated with methylchloroaluminum N-methoxy-N-methylamide as before to give the methoxyamide (XLIX). Silylation of (XLIX) with TBS-SO3CF3 as usual yields the protected amide (L), which is finally reduced with diisobutylaluminum hydride to the second building group, the aldehyde (LI).
