Intramolecular hydrogen bonding allows simple enaminones to structurally mimic the i, i+4, and i+7 residues of an α-helix
摘要:
An intramolecularly hydrogen bonded enaminone scaffold was designed and synthesized in order to mimic the i, i + 4, and i + 7 residues of an alpha-helix. The resonance stabilized vinylogous amide group serves as an aromatic ring isostere and allows the positioning and angular projection of the R-groups in a manner similar to an alpha-helix.

(1H, 19F and in some cases 11B) spectra of a number of borondifluoride complexes have been recorded. These are discussed in detail and related to the electron distribution in the various systems dealt with. Included are those borondifluorides obtained from a series of 1,3-diketones, methyl salicylate, and tropolone. Two novel borondifluorides derived from 3-anilino-1-phenyl and 3-benzylamino-1-phenylbut-2-enone
