Abstract: A copper(I)-mediated cross-coupling of stereodefined secondary alkyllithiums with bromoalkynes provided stereodefined alkynes with high diastereoselectivity (dr up to 98:2). This cross-coupling was extended to various secondary alkyllithiums bearing a remote oxygen functionality, and the alkyne… read more here.
