Biomimetic-Inspired Syntheses of Myrtucommuacetalone and Myrtucommulone J

Abstract

Driven by bioinspiration and appreciation of their structures, the first biomimetic total syntheses with structural revision of the acylphloroglucinols myrtucommulone J and myrtucommuacetalone, two biologically meaningful natural products, were achieved through a biosynthetic hemiacetalization/dehydration/[3 + 3]-type cycloaddition domino sequence with high step efficiency. These syntheses result in a corrected structure for myrtucommulone J.
