N2 - The aza-Wittig rearrangement of enantio-defined N,N-dipropargylic α-amino alkyllithiums, generated by tin-lithium exchange, are shown to afford [1,2]- and/or [2,3]-rearrangement products. Both aza-Wittig rearrangements proceed predominantly with inversion of configuration at the Li-bearing carbon terminus.
