The present invention discloses fused bicyclic 2-aryl- or 2-heteroarylthiazolyl compounds and their pharmaceutically acceptable salts and esters thereof, which are useful for inhibiting the growth of cancerous cells, inhibiting human breast carcinoma tumor growth in particular and to treat diseases or disorders associated with securin, including elevated securin levels.
Silyl ketene acetals are shown to be competent nucleophiles in Pd-catalyzed migrative C(sp3)–H arylations. Compared to the parent ester lithium enolates, they possess decreased reactivity but enhanced chemoselectivity. This behavior was exploited through the synthesis of valuable benzo-fused δ-lactones such as 1-isochromanones and dihydrocoumarins.
