The rapid cis-trans isomerization of α-anionic stilbene was regioselectively controlled by using flow microreactors, and its reaction with various electrophiles was conducted. The reaction time was precisely controlled within milliseconds to seconds at -50 °C to selectively give the cis- or trans-isomer in high yields. This synthetic method in flow was well-applied to synthesize precursors of commercial drug compound, (E)- and (Z)-tamoxifen with high regioselectivity and productivity.
Development and application of a direct vinyl lithiation of cis-stilbene and a directed vinyl lithiation of an unsymmetrical cis-stilbene

Equation Presented The vinyl deprotonation of cis-stilbene can be readily achieved using s-BuLi in THF at -25°C. The generated 1-lithio-1,2- diphenylethene undergoes an in situ Z-to-E isomerization, and subsequent reaction with electrophiles results in an efficient stereoselective synthesis of trisubstituted alkenes. A directed vinyl lithiation of the unsymmetrical cis-stilbene 2-styryl-phenyl-carbamic acid tert-butyl ester can be achieved regioselectively, thereby expanding this methodology for further synthetic applications in indole chemistry.

The crystal structure of 1,2,3-triphenyl-2-propen-1-ol, derived from the palladium-catalyzed reductive addition of phenyl iodide to 1,3-diphenyl-2-propyn-1-ol, has been determined using single-crystal X-ray diffractometric data (Cu-Kα): M = 286
