experimental part, p. 10650 - 10659 (2010/01/16)
A small library of 1,4-benzodioxins and 4H-1,4-benzoxazines was synthesized from the corresponding bis-allyloxy precursors by way of an initial isomerization to the bis-vinyloxy compounds, followed by a ring-closing metathesis using the second generation Grubbs' catalyst (G2). A related strategy, starting from benzene-1,2-dithiol and 2-mercaptophenol, afforded benzodithiin and 1,4-benzoxathiin, respectively.
Synthesis of 2H-1,5-benzodioxepin and 2,5-dihydro-1,6-benzodioxocin derivatives via ring-closing metathesis reaction

, p. 2631 - 2633 (2007/10/03)
The synthesis of various 2H-1,5-benzodioxepin and 2,5-dihydro-1,6- benzodioxocin derivatives is described. The key step involves the construction of seven- and eight-membered rings via ring-closing metathesis reaction.
THE CLAISEN REARRANGEMENT OF SOME ALLYL-β-NAPHTHYL ETHERS AND CYCLIZATION OF THE PRODUCTS
Prajer-Janczewska, Lidia,Wroblewski, Juliusz
, p. 1431 - 1437 (2007/10/02)
Some allyl-2-carboxy-3-hydroxy- as well as 2,3- and 2,7-diallyloxynaphtalenes were obtained.Respectively rearranged compounds were cyclized to naphthodihydrofuran rings.
