00925njm 22002777a 4500 dc Solas Luera, Marta author Renedo Peña, Lorena author Suárez Pantiga, Samuel author Sanz Díez, Roberto author 2023-05-24 A gold-catalyzed cascade double cyclization reaction has been designed to synthesize heterobiaryl compounds such as furanyl and pyrrolyl 2H-chromenes from bis(alkynyl)-1,2-diols and 1,2-amino alcohols. The starting materials are readily available from biomass platform molecules such as α-hydroxy acids and α-amino acids. The process involves an initial heterocyclodehydration step enabling the formation of the furan or pyrrole ring, followed by an alkyne hydroarylation to form the chromene core. 1615-4150 http://hdl.handle.net/10259/9336 10.1002/adsc.202300300 1615-4169 Annulation Chromenes Furans Gold Hydroarylation Pyrroles Synthesis of 4‐Furan‐ and 4‐Pyrrol‐3‐yl‐2H‐chromenes from Naturally‐occurring Compounds by Gold(I)‐Catalyed Domino Reactions
