O-Cinnamyloxy/geranyloxy/cyclohexenyloxy/cinnamoyloxy-acetophenones yielded pyrazol-heterocycles, all of which contained an angular methyl-attached pyranopyran unit with pyrazolones in the ionic liquid (IL), 1,8-diazabicyclo[5.4.0]undec-7-ene-8-ium acetat
Synthesis of Allyl- and Prenylcoumarins via Microwave-Promoted Tandem Claisen Rearrangement/Wittig Olefination
Schmidt, Bernd,Riemer, Martin
supporting information, p. 141 - 149 (2015/12/26)
Allyl, dimethylallyl, crotyl, and prenyl ethers of various aromatic ortho-hydroxy carbonyl compounds undergo a tandem sequence of Claisen rearrangement, carbonyl olefination, and cyclization upon microwave irradiation in the presence of a stabilized ylide. The products are multiply substituted 6- or 8-allylated or prenylated coumarins (2H-chromen-2-ones).
An easy construction of 8,12-dioxa-13- azatricyclo[8.3.1.02.7]tetradeca-2(7),3,5,13-tetraen-14-ones

8,12-Dioxa-13-azatricyclo[8.3.1.02.7]tetradeca-2(7),3,5,13-tetraen- 14-ones are obtained in moderate yield by treatment of oximes of o- allyloxyacetophenones with [hydroxy(tosyloxy)iodo]benzene in acetonitrile.
