Sharma, Nutan,Chundawat, Tejpal Singh,Mohapatra, Subash Chandra,Bhagat, Sunita
, p. 4495 - 4508 (2016)
An efficient and novel approach using highly versatile but less exploited monofluorinated α-oxoketene N,S-acetals as synthons for the synthesis of novel fluorinated multisubstituted pyrimidines and 1,5-benzodiazepines by cyclization with guanidine nitrate
In-Water Synthesis of 5-Thiolated 1,2,3-Triazoles from β-Thioenaminones by Diazo Transfer Reaction
Deng, Leiling,Cao, Xiaoji,Liu, Yunyun,Wan, Jie-Ping
, p. 14179 - 14186 (2019/11/05)
The synthesis of 1,2,3-triazoles with a sulfur-based side chain has been accessed with the metal-free annulation reactions of readily available β-thiolated enaminones and tosyl hydrazine. By these reactions with water as the only medium, a broad array of

An efficient methodology has been developed for the synthesis of a variety of novel trifluoroacetylated enaminones by using trifluoroacetic anhydride in DCE as solvent and DBU as a base via electrophilic trifluoroacetylation. X-ray crystallographic studie
Copper-mediated intramolecular oxidative C-H/C-H cross-coupling of α-oxo ketene N, S -acetals for indole synthesis
Huang, Fei,Wu, Ping,Wang, Liandi,Chen, Jiping,Sun, Chenglin,Yu, Zhengkun
, p. 10553 - 10560 (2015/02/19)
CuCl2-mediated intramolecular C-H/C-H cross-dehydrogenative coupling (CDC) of thioalkyl-substituted α-acetyl or α-aroyl ketene N,S-acetals afforded 2-thioalkyl indoles. Tunable C-S bond transformations of the resultant indoles led to highly fun
Reaction of lithioamino anions with α-oxoketene dithioketals: An improved and a new general method for the synthesis of α-oxoketene S,N- and N,N-ketals
Singh, Okram Mukherjee,Junjappa, Hiriyakkanavar,Ila, Hiriyakkanavar
, p. 3561 - 3565 (2007/10/03)
A new method has been developed for the preparation of α-oxoketene S,N- (A) and N,N-(B) ketals starting from α-oxoketene dithioketals by employing mild conditions. Thus, lithioamino anions 2a-c, 4 and 6 are treated with α-oxoketene dithioketals 1 to affor
Reaction of α-oxoketene dithioacetals with arylamines in the presence of BF3-OEt2 for the synthesis of ketene S,N-acetals
Kohra,Turuya,Kimura,Ogata,Tominaga
, p. 1293 - 1296 (2007/10/02)
Reaction of α-oxoketene dithioacetals with arylamines was accelerated with a catalytic amount of BF3-OEt2 to give the corresponding α-oxoketene S,N-acetals selectively in good yields.
