In this Communication, procedures for the selective synthesis of 4-arylbutanoic acids, 2-arylbutanoic acids, and 4-arylbutanals from the same allylbenzenes have been developed. With formic acid or TFBen as the CO surrogate, reactions proceed selectively and effectively under carbon monoxide gas-free conditions.

Methyl derivatives of indan-1-one were prepared as models to aid in interpreting the carbon-13 nuclear magnetic resonance ((13)C-NMR) spectra of pterosin-sesquiterpenes which were isolated from bracken fern, Pteridium aquilinum var. latiusculum.The chemical shifts of the carbons of the methylindan-1-ones were assigned by the proton decoupling technique.All the (13)C-NMR signals of the pterosin-sesquiterpenes were assigned by means of selective proton decouplings, and from the (13)C-(1)H long-range couplings and (13)C chemical shifts of the model compounds.Keywords - indan-1-one derivative; methylindan-1-one; pterosin-sesquiterpene; methylindan-1-one synthesis; (1)H-NMR; (13)C-NMR; selective decoupling; C-H decoupling
