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.

combination of the recently developed multicomponent construction of highly substituted 3,4-dihydropyridones with subsequent allylation and intramolecular Heck-type cyclization allows the straightforward construction of benzo[a]quinolizines, a class of polycyclic compounds that – despite their interesting pharmacological and photochemical properties – have little precedent in the literature.
