To improve the efficiency of the photocatalytic decarbonylation of cyclopropenones, the effects of substituents on cyclopropenone were explored. A benzothiophene-substituted aminocyclopropenone exhibited significantly improved decarbonylation efficiency t

A phototriggered dehydration condensation using an aminocyclopropenone has been developed. The UV irradiation of an aminocyclopropenone generated a highly reactive ynamine in situ and the dehydration condensation of a carboxylic acid and an amine coexisting in the reaction solution smoothly proceeded to afford an amide. This reaction is completely controllable by the ON/OFF states of a UV lamp.
6-Alkyl, alkoxy, or alkylthio-substituted 3-(4-methanesulfonylphenyl)-4-phenylpyran-2-ones: A novel class of diarylheterocyclic selective cyclooxygenase-2 inhibitors

A novel class of 3-(4-methanesulfonylphenyl)-4-phenylpyran-2-ones possessing a central six-membered lactone (pyran-2-one) ring system, in conjunction with C-6 alkyl (Me, Et or i-Pr), alkoxy (OMe, OEt or O-i-Pr), and alkylthio (SMe, SEt or S-i-Pr) substitu
Synthesis and Properties of 3-Acylmethylene-2-(2-hydroxy-1-alkenyl)-1-phenylcyclopropenes, a New Class of Stabilized Triafulvenes

, p. 367 - 372 (2007/10/02)
Triafulvenes of type 9 are obtained by reaction of dichloro(phenyl)cyclopropenylium cation 7 with two equivalents of silyl enol ethers 8.They are characterized by means of their spectroscopic data and by X-ray analysis of 9c as cyclic 7-hydroxy-2,4,6-hept
