    • In the absence of 4Å MS, the aldol reaction proceeded to completion in 6 h, giving a mixture of 7a and 8a in 45% yield/77% ee and 32% yield/76% ee, respectively.

    • Although the use of 1.5 equiv of 6a under otherwise identical conditions afforded silylated aldol adduct 7a in 78% yield with 86% ee, the reaction required 24 h to reach completion.
