متن کاملDomino retro Diels-Alder/Diels-Alder reaction: an efficient protocol for the synthesis of highly functionalized bicyclo[2.2.2]octenones and bicyclo[2.2.2]octadienones.
A novel and convenient approach, the domino retro Diels-Alder/Diels-Alder reaction sequence for highly stereo- and regioselective synthesis of various bicyclo[2.2.2]octenone and bicyclo[2.2.2]octadienone derivatives is presented. Thus, the masked o-benzoquinones (MOBs) 2a-e generated by the pyrolysis of the respective dimers 3a-e participated in this novel synthetic strategy with a variety of o...
متن کاملSynthesis of pyrrolo[2,1-a]isoquinolines by multicomponent 1,3-dipolar cycloaddition.
Pyrrolo[2,1-a]isoquinoline derivatives were synthesized by one-pot three-component reactions starting from isoquinoline, 2-bromoacetophenones and different non-symmetrical acetylenic dipolarophiles using 1,2-epoxypropane as solvent. The structure of the compounds was assigned by IR and NMR spectroscopy.
متن کاملAssociation between Neonatal Phototherapy and Cancer during Childhood
