The present disclosure provides novel selective phosphatase inhibitor compounds based on illudalic acid. The present disclosure provides a streamlined method of synthesizing illudalic acid and a method for synthesizing phosphatase inhibitor compounds. The method of this invention provides convergent benzannulation of β-keto amides and esters, followed by a one-pot reduction / hydrolysis sequence. The concise synthetic approach provided by this invention enables rapid assembly of illudalog compounds of this invention that are potent protein tyrosine phosphatase receptor-type D (PTPRD) inhibitors.

Developing an efficient, concise synthesis of the fungal natural product illudalic acid has been a long-standing challenge, made more pressing by the recent discovery that illudalic acid and analogs are selective phosphatase inhibitors. Syntheses of illudalic acid have become progressively more efficient over the decades yet remain strategically grounded in a 17-step synthesis reported in 1977. Here we validate

[reaction: see text] A convergent totalsynthesis of illudin C is described. The tricyclic ring system of the natural product was quickly assembled from cyclopropane and cyclopentene precursors via a novel oxime dianion coupling reaction and a subsequent intramolecular nitrile oxide-olefin cycloaddition.
