Chemical Communications | 2004

A mild and efficient procedure for α-bromination of ketones using N-bromosuccinimide catalysed by ammonium acetate

Kiyoshi Tanemura; Tsuneo Suzuki; Yoko Nishida; Koko Satsumabayashi; Takaaki Horaguchi

Cyclic ketones reacted with N-bromosuccinimide (NBS) catalysed by NH(4)OAc in Et(2)O at 25 degrees C to give the corresponding alpha-brominated ketones in good yields, while acyclic ketones were efficiently brominated in CCl(4) at 80 degrees C.

Synthetic Communications | 2005

Chemoselective Reduction of Aldehydes in the Presence of Ketones with NaBH4 in Polyethylene Glycol Dimethyl Ethers

Kiyoshi Tanemura; Tsuneo Suzuki; Yoko Nishida; Koko Satsumabayashi; Takaaki Horaguchi

Abstract Aldehydes and ketones were treated with NaBH4 in polyethylene glycol dimethyl ethers (PEGDME) to give the corresponding alcohols in good yields. Chemoselective reduction of aldehydes in the presence of ketones was described.

Journal of The Chemical Society-perkin Transactions 1 | 2001

Formation of adamantan-1-ols by the reactions of adamantanes with 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ) in trifluoromethanesulfonic acid

Kiyoshi Tanemura; Tsuneo Suzuki; Yoko Nishida; Koko Satsumabayashi; Takaaki Horaguchi

Adamantanes were treated with DDQ in trifluoromethanesulfonic acid followed by hydrolysis to give adamantan-1-ols in good yields.
