Oxidation of N-1-(tributylstannyl)alkyl carboxamides and carbamates with ammonium hexanitratocerate (IV) or ferrocenium hexafluorophosphate generates their N-acyliminium ions by the elimination of tributylstannyl radical under mild reaction conditions.The
Gold(I)/(III)-catalyzed synthesis of 2-substituted piperidines; valency-controlled cyclization modes
Morita, Nobuyoshi,Tsunokake, Tomonori,Narikiyo, Yuji,Harada, Mayuka,Tachibana, Tatsuyuki,Saito, Yuta,Ban, Shintaro,Hashimoto, Yoshimitsu,Okamoto, Iwao,Tamura, Osamu

Strategic use of hard gold(III) and soft gold(I) catalysts provides facile access to two types of 2-substituted piperidines from propargylic alcohols. Thus, heating propargylic alcohols in the presence of AuBr3 results in cyclization to furnish
Pd-catalyzed enantioselective aerobic oxidation of secondary alcohols: Applications to the total synthesis of alkaloids
Krishnan, Shyam,Bagdanoff, Jeffrey T.,Ebner, David C.,Ramtohul, Yeeman K.,Tambar, Uttam K.,Stoltz, Brian M.
supporting information; experimental part, p. 13745 - 13754 (2009/02/06)
Enantioselective syntheses of the alkaloids (-)-aurantioclavine, (+)-amurensinine, (-)-lobeline, and (-)- and (+)-sedamine are described. The syntheses demonstrate the effectiveness of the Pd-catalyzed asymmetric oxidation of secondary alcohols in diverse contexts and the ability of this methodology to set the absolute configuration of multiple stereocenters in a single operation. The utility of an aryne C-C insertion reaction in accessing complex polycyclic frameworks is also described.

, p. 1669 - 1672 (2007/10/03)
Organoindate(III) ionic liquid (BMI?InCl4) was successfully employed in the nucleophilic addition of allyltrimethylsilane, silyl enol ethers and ketene silyl acetals to in situ generated cyclic N-acyliminium ions at room temperature without the
