3-dimethylamino-2-isocyanoacylate is described. During the course of this reaction two heterocyclic moieties, a thiazole and a β-lactam ring, are formed simultaneously and under mild conditions. The increase in molecular complexity here is dramatic as 2 CN, 2 CS and 1 CC bonds are formed in a new ‘one-pot’ multicomponent reaction.
Design and synthesis of novel potent and selective integrin αvβ3 antagonists—Novel synthetic routes to isoquinolinone, benzoxazinone, and quinazolinone acetates
An unexpected ring contraction of benzazepinone based alpha(nu)beta(3) antagonists led to the design of quinolinone-type derivatives. Novel and efficient syntheticroutes to isoquinolinone, benzoxazinone, and quinazolinone acetates were established. Nanomolar alpha(nu)beta(3) antagonists based on these new scaffolds were prepared. Moreover, benzoxazinones 15a and 15b exhibited high microsomal stability
