ORGANOMETALLIC INDUCED SELF-CONDENSATION OF CARBOXAMIDES
Babudri, F.,Ciminale, F.,Nunno, L. Di,Florio, S.
, p. 557 - 561 (1982)
N,N-Disubstituted carboxamides containing α-hydrogen atoms undergo self-condensation reaction simply on treatment with Grignard reagents or n-BuLi in THF at room temp.The reaction is considerably influenced by steric hindrance at the α-carbon and the condensing agent utilized.A possible Claisen-type mechanism is also reported.
Synthesis and Reactivity of 4-Substituted-2,3-dihydrobenzo-1,4-thiazines
Florio, Saverio,Leng, John L.,Stirling, Charles J. M.
, p. 237 - 240 (2007/10/02)
A series of derivatives of 4H-2,3-dihydrobenzo-1,4-thiazine has been prepared. 4-Acetyl-2,3-dihydrobenzo-1,4-thiazine undergoes self-condensation by n-butylmagnesium bromide affording the corresponding 4-acetoacetyl-2,3-dihydrobenzo-1,4-thiazine, which, i
An Easy and Efficient Synthesis of 4H-Thiazoloquinolin-4-ones and 5H-1,4-thiazinoquinolin-5-ones
Babudri, Francesco,Di Nunno, Leonardo,Florio, Saverio
, p. 1273 - 1274 (2007/10/02)
The title heterocycles have been synthesized by a Claisen-type self condensation of acetylbenzothiazolines and acetyldihydrobenzothiazines and subsequent cyclization.
REACTION BETWEEN N-ACYL-2,3-DIHYDROBENZO-1,4-THIAZINE AND N-ACYLPHENOTIAZINE WITH ORGANOMETALLIC REAGENTS
Ciminale, Francesco,Dunno, Leonardo Di,Florio, Saverio
, p. 3001 - 3002 (2007/10/02)
The title N-acyl-derivatives react with n-BuLi and Grignard reagents leading to products, which, formally, can be considered as derived from a Claisen-type condensation reaction.
