First-time use of a palladium(II)–thiadiazole catalyst in the allylic oxidation of terminal olefins to linear allylic acetates. Employing this strategy, a range of allylic esters (20 examples) were synthesized in 43 % to 80 % yield with excellent regio- and stereoselectivities.

A novel annulation reaction of readily available tolylamides was catalyzed by Cu(OTf)2 in the presence of Selectfluor and water through successive intermolecular C-H activated dehydrogenative cross-coupling reactions of benzylic methyl C(sp3)-H and aromatic C(sp2)-H bonds, and subsequent intramolecular C-O bond formation (see scheme).

FOTOQUIMICA DE -TOLUIDIDAS DE ACIDOS αβ-INSATURADOS. INFLUENCIA DE LA ADICION DE CARBONATO POTASICO

Irradiation of the p-toluidides of crotonic and cinnamic acids (2a,c) gives rise predominantly to the cis isomers 5a,c, together with appreciable amounts of 4,6-dimethyl-3,4-dihydro-2-quinolone (6a) in the case of 2a.The corresponding photo-Fries products have not been detected, even when the irradiation is performed in the presence of K2CO3.By contrast, photolysis of the p-toluidides of methylcrotonic and phenylpropiolic acids (2b,d) gives rise to the o-aminophenones 7b,d (in addition to the quinolone 6b from 2b).For these two amides, as well as for acetanilide and benzanilide, the selectivity towards the acyl migration product markedly increases when the irradiation is performed in the presence of K2CO3.Key words: Enamides' photocyclization, photo-Fries, quinolones.
Synthesis of Benzoquinolizine Derivatives
Merchant, J. R.,Pathare, P. M.
, p. 471 - 472 (2007/10/02)
The reaction of α,β-unsaturated acids with aromatic amines in the presence of PPA affords directly benzo-quinolizines (I).The structures of all the compounds have been established on the basis of elemental analyses and spectral data.
