摘要:
The present invention provides for compounds of Formula (I)
wherein R
1
, R
2
, R
3
, m and n have any of the values defined in the specification, and pharmaceutically acceptable salts thereof, pharmaceutical compositions comprising the same, and methods of treating cystic fibrosis by administering a compound of the invention.
Starting from readily available 7-substituted 1-indanones, products with a tetracyclo[5.3.1.01,7 04,11 ]undec-2-ene skeleton were obtained upon irradiation at λ=350 nm (eight examples, 49-67 % yield). The assembly of the structurally complex carbon framework proceeds in a three-photon process comprising an ortho photocycloaddition, a disrotatory [4π] photocyclization, and a di-π-methane rearrangement
Phenylalkylketone mit halogeniertem Alkyl, die bisher überwiegend durch Fries'sche Verschiebung von Phenolestern dargestellt worden sind, lassen sich einstufig in hoher Ausbeute durch BF3‐Kondensation von Phenolen mit Halogenfettsäuren synthetisieren.
