coupling of formamides and isoindolinone-3-ols to provide C(3) primary/secondaryamine substituted isoindolinones. The transformation requires a stoichiometric amount of phenylboronic acid as a co-reactant. In the reaction, formamides act as the synthetic equivalent of primary/secondaryamines. The method is amenable for the synthesis of a combinatorial library of medicinally relevant C(3) amino substituted
