Control elements in the highly selective construction of contiguous tertiary and quaternary carbon centers by the tandem alkylation of α-alkylidene-γ-butyrolactone derivatives were studied.It is clarified that the stereochemical course of the reaction is rationalized by evaluating highly selective 1,2-, 1,3-, and 1,4-asymmetric inductions.
