Yamaguchi, Akitake published the artcileConformationally stable peptide macrocycles assembled using the Petasis borono-Mannich reaction, SDS of cas: 77128-73-5, the publication is Chemical Communications (Cambridge, United Kingdom) (2019), 55(71), 10567-10570, database is CAplus and MEDLINE.
Macrocyclization of linear peptide precursors using the Petasis borono-Mannich reaction affords a diverse range of macrocycles with an endocyclic amine. Anal. of the corresponding macrocyclic structures underscores that the hydrogen bond between an endocyclic amine and the adjacent amide NH is a powerful control element for conformationally homogeneous peptide macrocycles.
