The design of dipeptide helical mimetics, Part I: the synthesis of 1,6-disubstituted indanes
摘要:
The design and synthesis of conformationally restrained, non-peptide templates (1,6-disubstituted indanes) which allow the incorporation of two adjacent amino acid side-chains in an orientation similar to that found in alpha-helices is reported.

amines or vinyl anilines for the preparation of pyrrolidines or indolines, the intermolecular version is less studied. Herein, this electrochemical intermolecular oxidative annulation of anilines and alkenes for the preparation of indolines proceeded under external oxidant-free conditions. The most noteworthy achievement of our work is the facile generation of indolines with quaternary centers at the

We utilize a 1,6-disubstituted indane as a template onto which two amino acid side-chains are appended in an orientation which mimics that found in a protein alpha-helix motif.

A chemoselective fluorinative ring expansion has been realized using the hypervalent iodine (HVI) reagent p-TolIF2, which delivers β,β-difluoroalkyl arenes in yields up to 89% and allylic gem-difluorides in yields up to 78%. This rapid reaction exploits the ambiphilic nature of alkenes and allenes, and incorporates both fluorine atoms of the (difluoroiodo)arene in the products. The mechanism involves
