A new method for the synthesis of 3-thioazaspiro[4,5]trienones was developed using Pd nanoparticle catalysts, which are highly efficient, environmentally friendly and recyclable. Alkynes and thiophene phenols are effectively cyclized by Pd/ZrO2

PhI(OCOCF3)2 acts as both a nonmetal oxidant and an iodination reagent to trigger iodocyclization of N-arylpropynamides while selectively affording iodinated quinolin-2-ones or the spiro[4,5]trienone skeleton, depending on the substituent pattern. In cases where the Narylpropynamide bears a para-fluorine on the aniline ring, the spiro compound is formed via an exclusive defluorination process; otherwise, the product was quinolin-2-one.
Catalytic oxidation/C-H functionalization of N-arylpropiolamides by means of gold carbenoids: Concise route to 3-acyloxindoles
Qian, Deyun,Zhang, Junliang
supporting information; experimental part, p. 7082 - 7084 (2012/08/07)
An efficient catalytic C-H functionalization by means of gold carbenoids for the one-step synthesis of 3-acyloxindole derivatives has been developed. The reaction proceeds efficiently with extremely good substrate scope and significant opportunities for s
