Nguyen, Thi Thanh Binh published the artcileSynthesis of (Z) isomers of benzoheterocyclic derivatives of combretastatin A-4: a comparative study of several methods, COA of Formula: C8H5IO, the publication is Tetrahedron (2013), 69(10), 2336-2347, database is CAplus.
Several methods for the preparation of (Z) trimethoxystyrene derivatives I [R = H, X = O, S, N-Boc, NH; R = OMe, NO2, X = S] & II were investigated. After finding that the Wittig reaction led to unsatisfactory results, three different strategies were considered: a Suzuki coupling with a stereodefined monobromoalkene, a combination of hydrosilylation/vinylsilane hydrolysis and a palladium-catalyzed semi-hydrogenation step, using DMF/KOH as the hydrogen source. Our studies led us to prepare a series of diarylacetylene derivatives via a Sonogashira coupling reaction, and also to find out a copper-free basic cyclization leading to benzo[b]thiophenes. The final choice for the synthesis method of I & II strongly depends on the target compound but the semi-hydrogenation, which avoids the use of a toxic tin reducing agent, should be generally preferred.
