Chemical Correlation

The total stereocontrolled synthesis of the antibiotic spectinomycin is described, based on the regiospecific functionalization and manipulation of appropriate starting materials. The tertiary ketol rearrangement of the antibiotic and its derivatives was studied and the stereochemical identity of spectinoic acid was established by chemical correlation. Dihydrospectinomycin derivatives undergo unusual solvolysis reactions.

Phase Design

Ingenol is a diterpenoid with unique architecture and has derivatives possessing important anticancer activity, including the recently Food and Drug Administration–approved Picato, a first-in-class drug for the treatment of the precancerous skin condition actinic keratosis. Currently, that compound is sourced inefficiently from Euphorbia peplus. Here, we detail an efficient, highly stereocontrolled synthesis of (+)-ingenol proceeding in only 14 steps from inexpensive (+)-3-carene and using a two-phase design. This synthesis will allow for the creation of fully synthetic analogs of bioactive ingenanes to address pharmacological limitations and provides a strategic blueprint for chemical production. These results validate two-phase terpene total synthesis as not only an academic curiosity but also a viable alternative to isolation or bioengineering for the efficient preparation of polyoxygenated terpenoids at the limits of chemical complexity.
