The first biomimetic totalsyntheses of natural phloroglucinols tomentosones A and B and their analogues have been accomplished. The synthetic strategy primarily referred to the potential biosynthetic precursors and their possible sequence of segments assembly by chemological evolution of the structural entities and enabled rapid access of the titled compounds in a practical fashion.

Discovery and Biomimetic Synthesis of a Polycyclic Polymethylated Phloroglucinol Collection from <i>Rhodomyrtus tomentosa</i>
Inspired by a previously reported biomimetic synthesis study, four new naturally occurring phloroglucinol trimers 1–4 with unusual 6/5/5/6/6/6-fused hexacyclic ring systems, along with two known analogues (5 and 6) and two known biogenetically related dimers (10 and 11), were isolated from Rhodomyrtus tomentosa. Their structures and absoluteconfigurations were unambiguously elucidated by spectroscopic
