HCID 25215543(Z)-((2R,4R,6R)-2-Methoxy-2-((R)-3-(4-methoxybenzyl)-2-oxothiazolidin-4-yl)-6-((S)-3-methylpent-4-enyl)-tetrahydro-2H-pyran-4-yl) 3-Methylhepta-2,6-dienoate

Procedure

Triflate formation using the method shown in Example 22, with the modification that (R)-4-((2R,4S,6R)-4-hydroxy-2-methoxy-6-((S)-3-methylpent-4-enyl)-tetrahydro-2H-pyran-2-yl)-3-(4-methoxybenzyl)thiazolidin-2-one was substituted for (R)-4-((2R,4S,6R)-4-hydroxy-2-methoxy-6-(pent-4-enyl)-tetrahydro-2H-pyran-2-yl)-3-(4-methoxybenzyl)thiazolidin-2-one, followed by triflate displacement using the method shown in Example 23, afforded the title compound.
