Calix [4]bis(spirodienones) can perform as either 4p or 2p components in cycloaddition reactions with various carbo-and heterodienophiles and with 1,2-benzoquinones leading to the formation of highly functionalized macrocycles. In this Letter we report, highly regio-and stereoselective 1,3-dipolar c
