Product 1

HCID 59644042(R)-4-((2R,4R,6R)-4-Hydroxy-2-methoxy-6-phenethyl-tetrahydro-2H-pyran-2-yl)-3-(4-methoxybenzyl)thiazolidin-2-one

Procedure

Application of the method shown in Example 13, with the modification that (R)-4-((2R,4R,6R)-2,4-dihydroxy-6-phenethyl-tetrahydro-2H-pyran-2-yl)-3-(4-methoxybenzyl)thiazolidin-2-one is substituted for (R)-4-((2R,4S,6R)-2,4-dihydroxy-6-(pent-4-enyl)-tetrahydro-2H-pyran-2-yl)-3-(4-methoxybenzyl)thiazolidin-2-one, affords the title compound.
