Pd-Catalyzed Cross-Coupling of Potassium Alkenyltrifluoroborates with 2-Chloroacetates and 2-Chloroacetamides
摘要:
A protocol for the stereocontrolled synthesis of (E)- and (Z)-beta,gamma-unsaturated esters and amides is reported. 2-Chloroacetates as well as secondary and tertiary 2-chloroacetamides were successfully employed as electrophiles in the Suzuki-Miyaura cross-coupling reaction with potassium (E)- and (Z)-alkenyltrifluoroborates, affording the corresponding products in high yield.
Disclosed herein are compounds that inhibit the activity of particular tyrosine kinases. Methods for the preparation of such compounds are disclosed. Also disclosed are pharmaceutical compositions that include the compounds. Methods of using the compounds disclosed, alone or in combination with other therapeutic agents, for the treatment of tyrosine kinase-mediated diseases or conditions or tyrosine kinase-dependent diseases or conditions are provided.
