Abstract: Abstract A new method for the synthesis of benzocycloalkene derivatives is described, through the palladium-catalyzed one-pot two-step reactions of benzocyclic ketones, tosylhydrazide with aryl bromides. Palladium-carbene complex as an important intermediate undergoes migratory insertion to… read more here.

DOI: 10.1016/j.tetlet.2018.06.039
Abstract: Abstract A series of polysubstituted pyrrolo[3,2-d]pyrimidinedione derivatives have been synthesized in excellent yields. This prominent scaffold is obtained via an Al(OTf)3-catalyzed tandem addition-annulation sequence between propargylic alcohols and aminopyrimidines. The process is simple, facile, inexpensive,… read more here.

DOI: 10.1080/00397911.2020.1815784
Abstract: Abstract A method using PPh3/I2-catalyzed three-component Biginelli reaction of aromatic ketone, aromatic aldehyde and urea to synthesize4,6-diarylpyrimidin-2-(1H)-ones is described. Under the experimental conditions, the main reaction products are 4,6-diarylpyrimidin-2-(1H)-ones not 4,6-diaryl-3,4-dihydropyrimidin-2(1H)-ones. The advantage of this… read more here.
