Synthesis of 4-azepanones and heteroaromatic-fused azepines

Solvent and catalyst free ring expansion of indoles: a simple synthesis of highly functionalized benzazepines

Highly functionalized benzazepines have been synthesized from indoles via ring expansion. Ring contraction of benzazepines to indole derivatives has also been acheived in excellent yields.

One-pot high-throughput synthesis of a 160-membered library of methyl 3,5-diaryl-isoxazoline-5-carboxylate pharmacophores by a 2·2·2-component reaction

A simple and efficient methodology has been developed for the synthesis of methyl 3,5-diaryl-isoxazoline-5-carboxylates in a high-throughput fashion. This was accomplished in one-pot by a sequence of three 2-component reactions steps (2·2·2-CR), whereby compounds were obtained in overall 30-66% isolated yields. The functional group diversity was established by synthesizing a 160-membered library.
