## Abstract Except from 1,4,9,10‐anthracenetetrols, 9,10‐anthrahydroquinones (derived from the quinones **5a** and **18**– **21**) react with unhindered Michael acceptors such as acrylate, acrylonitrile, acrylaldehyde, and methyl vinyl ketone with addition at C‐9 or C‐10 to yield anthrones. The dir

Lithium diorganocuprates are now widely used in conjugate additions to a,a-unsaturated car-bony1 compounds' and in coupling reactions with alkyl halides2, allyli~acetates~, and other compounds possessing good leaving groups. Here we report a new reaction of lithium dialkylcuprates which is formally
The reaction of furan with a,~ansaturated carbonyl dienophiles catalyzed by KI0 montmorillonite in the absence of organic solvents produces the corresponding Diels-Alder adducts and, in the case of methyl vinyl ketone, Michael-type products, under much milder conditions than the conventional protoco
