A new route to functionalised oxazoles

, 1996
Functionalised oxazoles 4 are prepared from amides 1 by rhodium cartenoid N-H insertion reaction to give beta-carbonyl amides 3 followed by cyclodehydration with triphenylphosphine-iodine-triethylamine.

Modular Approach for Photoinduced Cycloaddition Enabling the Synthesis of Diverse Bioactive Oxazoles

The synthesis of bioactive oxazoles is often inefficient, and the reported methods remain largely unexplored for complex derivatives. To circumvent this issue, we have utilized a metal-free, photomediated [3 + 2] cycloaddition reaction between diazo ...
