Highly Stereoselective Synthesis of Trisubstituted cis-[3]Cumulenols from Alkynylated Oxatitanacycles in the Presence of Lewis acids
ORGANOMETALLICS（2010）
摘要
A highly efficient and stereoselective method for the synthesis of trisubstituted cis-[3]cumulenols via oxatitana-cycles derived from titanium-mediated coupling of 1,3-butadiynes with aldehydes or ketones promoted by Lewis-acids is described.
