Efficient Solid Phase Synthesis of Diverse Quinazolinones
Further Information
Publication History
Publication Date:
31 December 2000 (online)
Various quinazolinones were synthesized by cyclocondensation of anthranilamides with a variety of orthoformates on solid supports. Alkyl, aryl and alkoxy groups can substitute at 2 position of quinazolines with this method. The reactions proceeded smoothly under mild acidic conditions and the products exhibited excellent purity. Unlike previously reported solid phase quinazolinone syntheses, this synthetic strategy does not require an oxidation step. The approach is applicable to the synthesis of a wide range of quinazolinones, including molecules that are susceptible to oxidation.
