The total synthesis and biological evaluation of the marine sesterterpenoid ansellone A (1), an HIV latency-reversing agent, and its analogues are reported. The key to the success of this synthetic route is a Prins cyclization reaction enabled by the strategic use of the TfO group for stabilization of the acid-labile tertiary allylic alcohol. The SAR study found the alcohol analogue to exhibit more potent activity than 1.
