dc.description.abstract	A calix[4]arene derived bis(spirodienone) acts as the 2 pi component in a cycloaddition reaction with two molecules of 3,5di-tert-butyl-1-2-benzoquinone in the [2+4] manner leading to macrocycles with a benzodioxin moiety. A theoretical rationalization of the results suggested a sterically encumbered regioselective pathway, which gives sterically crowded products.	en_US
