DOI: 10.1016/j.tet.2019.130559
Abstract: Abstract 4-Bromo-2,3,5-trichloro-6-iodopyridine was studied as a new substrate in chemoselective Sonogashira reactions. This approach provides an efficient access to non-symmetrical mono-, di-, tri- and pentaalkynylated pyridines in good yields. Selected pentaalkynylated pyridines were studied with… read more here.

DOI: 10.1039/d2cc04909k
Abstract: A bifunctional tertiary amine-squaramide-catalyzed enantioselective Mannich-type addition of available allomaltol to N-protected aldimines was developed. The resulted adducts were readily transformed into non-proteinogenic α-amino acids and their derivatives were not easily accessible by other methods… read more here.

DOI: 10.1039/d2sc04722e
Abstract: Here, we report a new on-surface synthetic strategy to precisely introduce five-membered units into conjugated polymers from specifically designed precursor molecules that give rise to low-bandgap fulvalene-bridged bisanthene polymers. The selective formation of non-benzenoid units… read more here.
