    • We have also made the reactions of 1c with MeLi (1.3 eq) in the presence of methylaluminum bis (2,4,6-tritert-butyl-phenoxide). Nevertheless the use of MAT did not improve the stereoselectivity and the chemical yield was even lower than under other conditions used in Table 1.

    • We used the protected β-ketoester 4 as the starting material to avoid the presumably negative influence of the free carbonyl on the stereoselectivity of the β-kelosulfoxide reduction. Nevertheless, Solladié showed that this protection was not necessary (Solladié, G.; Ghiatou , N. Tetrahedron Lett., 1992, 33, 1605).
