    • Caution: During the workup of the transesterification reaction of 3, viz., the filtration of the reaction mixture through a Celite pad followed by concentration of the filtrate in vacuo, we occasionally observed the formation of 3-acetoxymethyl-3-(furoyloxymethy)oxindoles in variable yields. This often occurred when we used a large excess of 5 (for instance, 5 equiv), which resulted in decreasing yields of 2. The side-product seemed to be generated by the acetylation of the optically active 2. The remaining 5 was likely to be involved to some degree, although we have not specified the exact factor that induces the undesired reaction. The side-reaction could be suppressed by stirring the above-mentioned filtrate with water for 30 min to decompose 5 and to extract the resultant 2-furoic acid with the aqueous phase (for details, see Experimental Section).

    • 3 in MeOH at room temperature caused a significant racemization of 9 (12% ee) probably via the retro-aldol-aldol reaction.10c The use of Dibal-H successfully cleaved the ester bonding of 8 to give 9 (99% ee, 50% yield, 77% yield based on the consumed 8) and the recovered 8 (35% yield).
