    • 9. Inanaga has already proposed such a cyclic chelate model for the formation of a (cis)-γ-butyrolactone from methyl crotonale and cyclohexylcarboaldehyde. Furthermore, he reported the 1:1 ratio of trans-/cis-diastereomers in the presence of large excess of HMPA to break such a cyclic chelate (A ). (a) Otsubo, K.; Inanaga, J.; Yamaguchi, M.
