DOI: 10.1021/jacs.1c04835
Abstract: We present a modular, synthetic entry to polysubstituted pyrroles employing readily available 2,5-dihydrothiophenes. Ring-opening of the heterocycle provides access to a panel of 1,3-dienes which undergo pyrrole formation in the presence of inexpensive chloramine-T trihydrate.… read more here.

Abstract: Calix[3]pyrroles were synthesized for the first time. These macrocycles display versatile guest binding ability based on the bridges connecting the two α-positions of the tripyrrane moiety e.g. with an ethene bridge they showed colorimetric sensing… read more here.
