AlCl3 catalyzed coupling of: N-benzylic sulfonamides with 2-substituted cyanoacetates through carbon-nitrogen bond cleavage
Hu, Chen,Hong, Gang,Qian, Xiaofei,Kim, Kwang Rim,Zhu, Xiaoyan,Wang, Limin

A new cross-coupling reaction of N-benzylic sulfonamides with 2-substituted cyanoacetates for the synthesis of 2-substituted benzylbenzene was reported. In the presence of AlCl3, a broad range of N-benzylic sulfonamides reacted smoothly with 2-substituted cyanoacetates to afford structurally diverse benzylbenzenes in moderate to excellent yields. The conversion could be enlarged to gram-scale efficiently. The practicability of this approach was further manifested in the synthesis of a related bioactive agent with high anti-inflammatory activity.

supporting information, p. 875 - 883 (2015/08/24)
The synthesis of thiazoles and thiophenes starting from nitriles, via a modified Gewald reaction has been studied for a number of different substrates. 1,4-Dithiane-2,5-diol was used as the aldehyde precursor to give either 2-substituted thiazoles or 2-substituted aminothiophenes depending on the substitution of the α-carbon to the cyano group.
Efficient preparation of α,α-dialkyl-α-(phenylselanyl) acetates and α,β-unsaturated esters from the corresponding α,α-dialkyl-α-cyanoacetates by a lithium naphthalenide induced reductive selenenylation process
Ko, Yen-Chun,Zhu, Jia-Liang
, p. 3659 - 3665 (2008/09/19)
An array of α,α-dialkyl-α-(phenylselanyl)acetates has been synthesized very efficiently from readily available α,α- dialkyl-α-cyanoacetates, by use of lithium naphthalenide induced reductive α-selenenylation as a key operation. Moreover, the selanyl esters thus generated in situ could be converted further, in a one-pot treatment with hydrogen peroxide and acetic acid, into the corresponding α,β- unsaturated esters in moderate to high yields. The C=C bond formation was highly regio- and/or diastereoselective in some cases. Georg Thieme Verlag Stuttgart.
Synthesis of variously 9,9-dialkylated octahydropyrimido [3,4-a]-s-triazines with potential antifungal activity
Ghaib, Amar,Menager, Sabine,Verite, Philippe,Lafont, Olivier
, p. 109 - 116 (2007/10/03)
9,9-Dialkyloctahydropyrimido[3,4-a]-s-triazines were synthesized by iminodimethylation reaction between a 5,5-dialkyl-6-aminopyrimidine-2,4(3H,5H)-dione, a substituted aniline and two moles of formaldehyde. The synthesis of 5,5-dialkyl-6-aminopyrimidinedione consisted of the condensation of urea with ethyl 2,2-dialkylcyanoacetates. 18 Octahydropyrimido[3,4-a]-s-triazines were synthesized and compounds resulting from a supplementary aminomethylation were also obtained. Most of these compounds were tested for antifungal activity in vitro. Only 9,9-dibutyl-6,8-dioxo-3(2-chlorophenyl)2,3,4,5,6,7,8,9-octahydropyrimido[3, 4-a]-s-triazine showed some activity against Microsporum canis.

, p. 5121 - 5124 (2007/10/03)
In an organic solvent system, 3-oxo-3-arylpropanenitriles are C- alkylated by bakers yeast. The reported mechanism for bakers yeast alkylation of ethyl cyanoacetate (13), in an aqueous system, has been revised.

, p. 4195 - 4198 (2007/10/02)
Active methylene compounds undergo chemical condensation in water with aldehydes derived from yeast oxidation of the corresponding alcohols. Unsaturated compounds so obtained are then further reduced by yeast.
