We report an ecofriendly synthetic approach for the fabrication of biogenic gold nanoparticles (AuNPs) using electron‐rich sea cucumber extract as a bio‐reductant and stabilizing agent in reducing gold cations into AuNPs at the optimal conditions. The produced AuNPs are spherical in shape with an average particle size of 11 ± 1.5 nm in transmission electron microscopy (TEM) and exhibited a crystal structure of face‐centered cubic in X‐ray diffraction (XRD) analyses. Our results indicated that bioinspired AuNPs demonstrate superior catalytic activity in the safe and facile one‐pot synthesis of polyhydroquinoline derivatives under solvent‐free reaction conditions. This green route encompasses multiple benefits including highly recyclable bioinspired catalyst (5 cycles), short reaction times, convenient workout, high to excellent product yields (82%–97%), and nonhazardous conditions.
