Fragranol A: A new class of spiro-triflavanoid hybrid with an unprecedented carbon skeleton from Anneslea fragrans
© 2020 Elsevier Ltd Phytochemical investigation of Anneslea fragrans twigs resulted in the discovery of fragranol A (1), a new class of structurally challenging and sterically hindered “spiro-triflavanoid” type compound possessing an unprecedented carbon skeleton. Fragranol A (1) consists of 45 carb...
