An interesting entry to functionalized dihydropyrans has been intensively studied by Tietze in the 1990s using a three-component domino-Knoevenagel Hetero-Diels-Alder sequence. The overall transformation involves the transient formation of an activated heterodienophile by condensation of simple aldehydes with 1,3-dicarbonyls such as barbituric acids [127], Meldrum s acid [128], or activated carbonyls. In situ cycloaddition with electron-rich alkenes furnished the expected functionalized dihydropyrans. Two recent examples concern the reactivity of 1,4-benzoquinones and pyrazolones as 1,3-dicarbonyl equivalents under microwave irradiation. In the first case, a new three-component catalyst-free efficient one-pot transformation was proposed for the synthesis of pyrano-1,4-benzoquinone scaffolds [129]. In this synthetic method, 2,5-dihydroxy-3-undecyl-1,4-benzoquinone, paraformaldehyde, and alkenes were suspended in ethanol and placed under microwave irradiations to lead regioselectively the corresponding pyrano-l,4-benzoquinone derivatives (Scheme 38). The total regioselectivity was... 

Resorcinarenes, macromolecules of type III, are an interesting class of compounds through their prospective applications as molecular devices for molecular recognition, HPLC experiments, ion transport across membranes, etc. Much attention has recently been paid to solid state NMR studies of the tetra(C-undecyl)calix[4]resorcinarene host obtained from resorcinol and lau-ryl aldehyde (Scheme 8) [55,56]. 

Undecylenic acid is important as a starting material for a number of fragrance materials, some of which are shown in Figure 4.76. The two aldehydes are obtained by simple functional-group manipulation. Both are known by trivial, and somewhat confusing, names in the industry 10-Undecenal as Aldehyde Cll undecylenic or simply Aldehyde Cl 1, and undecanal as Aldehyde Cll undecylic. The fact that the term...
