Skeletal rearrangement in Biginelli reaction for the synthesis of chromenoquinoline fused spirohydantoins and their in silico cytotoxicity study

Scientific Reports
Although Biginelli reaction is known to generate dihydropyrimidinones having wide arrays of phramacological properties, herein we report an unprecedented skeletal rearrangement in Biginelli reaction to synthesize pharmacologically versatile imidazolidine-

New polyamides based on 1,3-bis(4-carboxy phenoxy) propane and hydantoin derivatives: synthesis and properties

Bulletin of the Chemical Society of Ethiopia, 2010
Six new polyamides 5a-f containing flexible trimethylene segments in the main chain were synthesized through the direct polycondensation reaction of 1,3-bis(4-carboxy phenoxy) propane 3 with six derivatives of hydantoins 5a-f in a medium consisting of N ...
