    • The yield of propargyl alcohol 6 was diminished by small amounts (< 10%) of Meerwein-Ponndorf-Verley reduction of 1a, presumably by intermediate A: Diagram presented However, neither side product was observed when the title reaction reaction was run using the conditions described in eq 1, further supporting our mechanistic interpretations.

    • Only two examples of enantioenriched glycolate aldolates of this type have been prepared, to our knowledge. One was by a chiral auxiliary method: Murata, Y.; Kamino, T.; Hosokawa, S.; Kobayashi, S. Tetrahedron Lett. 2002, 43, 8121. The other was prepared by a direct catalytic method involving chiral zinc complexes: Kumagai, N.; Matsunaga, S.; Kinoshita, T.; Harada, S.; Okada, S.; Sakamoto, S.; Yamaguchi, K.; Shibasaki, M. J.
