Herein we report a diastereoselective synthesis of medium-sized carbocycle-fused piperidines via [1,n (n = 6, 7)]-[1,5]-sequential hydride shift triggered double C(sp3)-H bond functionalization. When cinnamylidene malonates having N,N-dibenzyl propylamine moiety were treated with 5 mol % of Yb(OTf)3, a [1,6]-[1,5]-sequential hydride shift/cyclization process proceeded to afford seven-membered carbocycle-fused piperidines with excellent diastereoselectivities. This sequential system was applicable to the synthesis of eight-membered carbocycle-fused piperidines by an unprecedented [1,7]-[1,5]-sequential hydride shift/cyclization process.

The enantioselective oxyarylation of (E)-6-aryl-1-silyloxylhex-3-ene was achieved using a lactate-based chiral hypervalent iodine(III) reagent in the presence of boron trifluoride diethyl etherate. The silyl ether promotes the oxidative cyclization, and enhances the enantioselectivity. In addition, the corresponding aminoarylation was achieved.

Intramolecular palladium-catalyzed aryl amination and aryl amidation
Wolfe, John P.,Rennels, Roger A.,Buchwald, Stephen L.
, p. 7525 - 7546 (2007/10/03)
Upon treatment with a palladium catalyst and a suitable base, aromatic halides undergo intramolecular substitution to form five, six, and seven-membered rings. In a similar fashion aryl halides with pendant amides or sulfonamides are cyclized to form five and six-membered rings.
