The diversity of drimane hydroquinones was significantly expanded by the facile construction of (+)-chromazonarol relevant natural products, isomers, and analogues for the discovery of new pharmaceutical leads. The structure-activity relationship of (+)-c
Process Development and Good Manufacturing Practice Production of a Tyrosinase Inhibitor via Titanium-Mediated Coupling between Unprotected Resorcinols and Ketones

A concise and economically attractive process for the synthesis of a novel tyrosinase inhibitor has been developed and implemented on a multikilogram scale under GMP. A major achievement to the success of the process is the development of a direct coupling between free resorcinol and ketone. First developed under basic conditions, this coupling has been turned to a novel titanium(IV) mediated process allowing good selectivity, easy isolation, and high atom efficiency. Other key steps feature an alkene reduction by palladium catalyzed transfer hydrogenation and a urea formation using N,N′-disuccinimidyl carbonate as the carbonyl source. This route allowed us to produce kilogram batches of the candidate to support preclinical and clinical studies.

Enantioselective synthesis, stereochemical correction, and biological investigation of the rodgersinine family of 1,4-benzodioxane neolignans

The enantioselective synthesis and chiroptic analysis of all members of the rodgersinine family of 1,4-benzodioxane neolignans has been achieved. ECD spectra and optical rotation analysis determined that the previously published stereochemistry of trans-rodgersinines A and B was incorrect. The cis-rodgersinines A and B did not follow the model ECD study commonly used to assign the absolute stereochemistry of 1,4-benzodioxane natural products. This finding has implications on the absolute stereochemistry of other natural products of this type. Additionally, the rodgersinines were found to have anti-HCV activities.
