The generality of the N-arylation was then evaluated with substrates 3b-o, carrying a variety of aryl groups. Satisfyingly, transfer of Ar 2 with varied electronic properties proceeded smoothly, delivering a range of electron deficient and electron rich products 5h-n in 61-92% yields. Even functional groups susceptible to nucleophilic additions, such as esters and amides, remained unaltered in the products 5o and 5p. The sterically congested ortho-Me product 5n could also be synthesized, whereas mesityl substrate 3k proved unreactive under the current conditions. The pyridinyl salt 3l-OTs was also unproductive, as the reaction with piperidine led to complex reaction mixtures. Substrates 3 with alterations on Ar 1 efficiently underwent the desired transformation, yielding products 5q-s in 78-86% yield. Next, our focus was directed towards prospective nucleophiles for the ring opening of 4 (Scheme 3). To make this step efficient for less potent nucleophiles than piperidine, two methods were developed. For aliphatic and aromatic amines, the reactions were performed for 2-6 h at 50-60 °C (method A), to give Scheme 3. Scope of products 5 from variation of substrates 3.
