Metallic Samarium- and Iodine-Promoted Facile and Efficient Synthesis of
Alkenes from the Acetates of Baylis—Hillman Adducts. — In the
28- 093 Trisubstituted
presence of samarium and catalytic amounts of iodine, acetates of Baylis—Hilman adducts, e.g. (I), undergo reductive elimination to give (E)-methylcinnamic esters such as
(II). The use of equimolar amounts of iodine and Sm results in formation of allylic
iodide derivatives. — (LI, J.; XU, H.; ZHANG*, Y.; Tetrahedron Lett. 46 (2005) 11,
1931-1934; Dep. Chem., Zhejiang Univ., Hangzhou 310028, Peop. Rep. China; Eng.)
