A concise and efficient synthesis of isoindolin-1-ones. New synthetic approach to the polycyclic framework of vitedoamine A
摘要:
A concise and efficient synthesis of 2,3-dihydro-1H-isoindol-1-ones based upon the Parham-type cyclization of iodinated benzyldicarbamates is reported. The synthetic potential of this approach was further emphasized by the assembly of the polycyclic framework of vitedoamine A. (c) 2007 Elsevier Ltd. All rights reserved.
The photochemically initiated dehydro-Diels-Alder (PDDA) reaction is an efficient and versatile method for the prepa- ration of biaryls. The ring closure may take place both inter- and in- tramolecularly, of which the intramolecular variant is more productive from the preparative point of view. A variety of linkers can be employed to connect the ynone moiety, which acts as the chromophore, with another
