the Heck: The heptacyclic fungal alkaloid communesin F was the target of a total synthesis featuring a rare example of an intramolecular Heck cyclization of a tetrasubstituted alkene, a reductive cyclization of an N‐Boc aniline, a stereoselective C allylation of a lactam, and an azide reduction/N‐Boc‐δ‐lactam ring opening sequence (see scheme, BOM=benzyloxymethyl).
