trans Deformation of a Carbon-Carbon Triple Bond in Response to Incipient Nucleophilic Attack: the X-Ray Crystal Structure of Ethyl 3-(2-Nitrophenyl)propynoate at 150 K
Rice, Craig R.,Wallis, John D.
, p. 572 - 574 (1993)
In the title compound 1 the electron-deficient alkyne bond shows a pronounced trans distortion in response to an adjacent electron rich nitro O atom, suggesting that the more favourable reaction coordinate for addition of nucleophiles to activated alkynes involves trans rather than cis addition.
The reaction of substituted ethyl α-bromocinnamates with tetrabutyl ammonium fluoride

The reaction of ethyl α-bromocinnamates with tetrabutyl ammonium fluoride (TBAF) was influenced largely by the position of the substituent at the phenyl ring. While the substrates without an ortho substituent at the phenyl ring were transformed to the cor
Synthesis of 3-arylindole-2-carboxylates via copper-catalyzed hydroarylation of o-nitrophenyl-substituted alkynoates and subsequent cadogan cyclization

A two-step route to biologically important 3-arylindole-2-carboxylic esters has been successfully established: o-nitrophenyl-substituted alkynoates underwent copper-catalyzed hydroarylation in the presence of commercially available arylboronic acids to afford 3,3-diarylacrylates, which were then converted to indolecarboxylates via a modified Cadogan cyclization using a molybdenum catalyst and triphenylphosphine.

Preparation of α-bromoacrylates: One-pot procedure for the synthesis of conjugated acetylenic carboxylates from aldehydes with Ph3P/ Br3CCO2Et
Kim, Joong-Gon,Dong, Ho Kang,Doo, Ok Jang
, p. 443 - 447 (2008/04/01)
We have established the optimal conditions for the Wittig reaction for synthesizing α-bromoacrylates with a high selectivity, and developed a simple and efficient one-pot procedure for preparing various conjugated acetylenic carboxylates in moderate to high yields. Georg Thieme Verlag Stuttgart.
