An efficient phosphaannulation via palladium(II)‐catalyzed CH activation/oxidative cyclization by the 6‐endo mode is reported for the synthesis of 3‐substituted phosphaisocoumarins from the reaction of arylphosphonic acids with unactivated alkenes under aerobic conditions. Also, α,α‐disubstituted benzylphosphonic acids were phosphaannulated with unactivated alkenes, producing phosphaisochromanones

ins and their derivatives was developed through a palladium-catalyzed oxidative cyclization reaction of a wide range of arylphosphonic acid monoethyl esters with activated and unactivated 1,3-dienes, including 1-aryl-substituted 1,3-dienes and 1-alkyl-substituted 1,3-dienes, thus opening a new avenue for the synthesis of phosphaheterocyclic compounds.
3-phosphoindole compounds for the treatment of retroviral infections, and particularly for HIV, are described. Also included are compositions comprising the 3-phosphoindole derivatives alone or in combination with one or more other anti-retroviral agents, processes for their preparation, and methods of manufacturing a medicament incorporating these compounds.
Antibacterial activity is exhibited by β-lactams having a phosphinic or phosphonic substituent in the 1-position and an acylamino substituent in the 3-position.
