We applied a multicomponent approach to access a library of densely functionalized homo- and hetero-multivalent glycomimetics comprising aldehyde, amine, and isocyanide components related to isopropylidene-protected d-fructose, l-sorbose, d-galactose, and d-allose. Passerini products were obtained in very good yields (up to 78%) and high diastereoselectivities (up to 982). Three types of products were obtained by the Ugi reaction; along with the "classical" four-component product, α-acylaminoamides, a three-component α-

An LED emergency driver is an essential device that ensures lighting remains operational during power outages. It converts standard LED fixtures into emergency lighting, providing backup power for a specific duration, usually 90 minutes. When the main power fails, the LED emergency driver automatically switches to battery mode, keeping lights on for safe evacuation or continued visibility. These drivers are ideal for commercial buildings, hospitals, and public spaces, ensuring compliance with safety regulations. They are energy-efficie
