To extend the synthetic applicability of this method, we employed a set of substituted VBX and VBO reagents in vinylations of DHPs 1o and 1r (Scheme 3). As VBO reagents were superior coupling partners with acyclic alkyl-DHPs, we initiated the scope studies with disubstituted (E)-VBO 4. The reactions provided the desired olefins 5a-5c in moderate to good yields with complete E/Z stereoselectivity. X-ray diffraction analysis further confirmed the E geometry in 5a. Notably, also a trisubstituted (Z)-VBO underwent stereoselective C-C coupling to give (Z)-alkene 5d in 84% yield.
