Tertiary selenoamide compounds are useful superoxide radical scavengers in vitro

Takahashi, Hitoe,Nishina, Atsuyoshi,Kimura, Hirokazu,Motoki, Kenji,Koketsu, Mamoru,Ishihara, Hideharu

, p. 207 - 211 (2004)

We investigated the scavenging effects of tertiary selenoamide compounds for super oxide radicals using a highly sensitive and quantitative chemiluminescence method. At 333 nM, tertiary selenoamide compounds scavenged 25.8-81.6% of O2-/su

Copper(0)-induced deselenative insertion of N,N-disubstituted selenoamides into acetylenic C-H bond leading to propargylamines

Mitamura, Takenori,Ogawa, Akiya

supporting information; experimental part, p. 2045 - 2048 (2009/10/24)

Upon heating at 110 °C in the presence of copper(0) powder, terminal acetylenes undergo a novel deselenative C-H bond insertion reaction of N,N-disubstituted selenoamides, affording the corresponding propargylamines in good to excellent yields, selectivel

Copper(0)-induced aminocyclopropanation of olefins via deselenation of N,N-disubstituted aromatic selenoamides

Mitamura, Takenori,Nomoto, Akihiro,Sonoda, Motohiro,Ogawa, Akiya

experimental part, p. 9983 - 9988 (2009/04/03)

Upon heating of a mixture of N,N-disubstituted aromatic selenoamides and several electron-deficient olefins in the presence of copper(0) powder, a novel deselenative cyclopropanation takes place to afford the corresponding aminocyclopropanes in good yield

Facile conversion of amides and lactams to selenoamides and selenolactams using tetraethylammonium tetraselenotungstate

Saravanan, Vadivelu,Mukherjee, Chandan,Das, Saibal,Chandrasekaran, Srinivasan

, p. 681 - 683 (2007/10/03)

Chloroiminium salts generated in situ from amides and lactams using (COCl)2 or POCl3 react very readily with the new selenium transfer reagent, tetraethylammonium tetraselenotungstate, (Et 4N)2WSe4, 1

Facile synthesis of N,N-dialkylselenoamides from amides

Koketsu, Mamoru,Okayama, Yoshihiro,Aoki, Hiroshi,Ishihara, Hideharu

, p. 195 - 198 (2007/10/03)

The synthesis of the N,N-dialkylselenoamides from amides was discussed. These selenoamides were chlorinated with oxalyl chloride and then they were allowed to react with LiAlHSeH to afford the corresponding N,N-dialkylamides in moderate to good yields. Af
