How Is Phloroglucinol Made?

In Pseudomonas fluorescens, biosynthesis of phloroglucinol is performed with a type III polyketide synthase. ... Then decarboxylation followed by the cyclization of the activated 3,5-diketoheptanedioate product leads to the formation of phloroglucinol.

What is the structure of phloroglucinol?
