Key Word Index-Ferula communis; Umbelliferae; prenylated coumarins; ferprenin; ferulenol.The structure of ferprenin, a prenylated coumarin from Ferula communis, has been established from spectral data, and by synthesis from E,E-farnesal and 4-hydroxycoumarin.Ferprenin could also be obtained from ferulenol, the major constituent of the plant investigated, by a Cr(6+)-mediated oxidative cyclization, for which a possible mechanism is proposed.
Environmentally benign, one-pot synthesis of pyrans by domino Knoevenagel/6π-electrocyclization in water and application to natural products

In water medium, environmentally benign, facile, and efficient synthesis of pyrans was achieved in good yields by the reactions of a variety of cyclic 1,3-dicarbonyls with several α,β-unsaturated aldehydes. The key strategy was a formal [3+3] cycloaddition by domino Knoevenagel/6π- electrocyclization. This methodology was applied to the synthesis of biologically interesting pyranocoumarin, pyranoquinolinone, and pyranonaphthoquinone derivatives along with selected natural and non-natural products.
