It has been found that the E lithium enolate of ethyl propionate reacted with ethyl (E)-crotonate gave anti and syn 1,4-adducts in a ratio of 71:29. The stereoselectivity was increased to 10:1 if HMPA was added after enolate formation and further increased to >20:1 if HMPA was added prior to enolate formation. See: Yamaguchi, M.; Tsukamoto, M.; Tanaka, S.; Hirao, I. Tetrahedron Lett. 1984, 25, 5661.

It has been suggested that HMPA (in THF, a polar aprotic solvent) does not disrupt enolate tetramers. See: (a) Amstutz, R.; Schweizer, W. B.; Seebach, D.; Dunitz, J. D. Helv. Chim. Acta 1981, 64, 2617.

Further evidence for other Michael adducts without X-ray crystallographic analysis were confirmed by NOE experiments of the corresponding products after hydrolysis and lactonization [eqs 3 and 4]. For details, see Supporting Information.
