Abstract

Abstract The total synthesis of Hirtellanine A was accomplished by two different synthetic approaches. Hirtellanine A was assembled using a one-pot, tandem acid-mediated deprotection and tautomerization cascade starting from quinone derivative 23. The key features of the synthesis include a Houben–Hoesch reaction of aryl cyanide 3 with phloroglucinol, a one-pot sequential boronation, a Suzuki–Miyaura cross-coupling of aryl ...
