An unprecedented remote amide-directed palladium-catalyzed intermolecular highly selective benzylic C-H amination with N-fluorobenzenesulfonimide is developed, which represents the first direct benzylic C-H amination with a non-nitrene nitrogen source. This methodology provides a novel approach to circumvent the common ortho aromatic C-H selectivity in directed palladium catalyzed C-H functionalization.

Densely substituted styryl sulfone 20 is shown to undergo double annulation with phthalide 21 to give, in one-pot operation and in excellent yield, the benzonaphthopyranone scaffold 22 of gilvocarcins.
Synthesis of The Gilvocarcin-M Aglycone

, p. 5435 - 5436 (2007/10/02)
The synthesis of the aglycone of the antibiotic Gilvocarcin-M by a sequential Meerwein Diels-Alder route is reported.The D-ring of the aglycone is attached by a halogen atom directed Meerwein arylation reaction and the A-ring is attached by a halogen atom directed Diels-Alder reaction.In the key step the directing chlorine atom is removed by a new thiophenylation reduction sequence.
Synthesis of maytansinoids: the aromatic moiety of maytansine
