Synthesis of esters of diaminotruxillic bis-amino acids by Pd-mediated photocycloaddition of analogs of the Kaede protein chromophore

Beilstein Journal of Organic Chemistry, 2020
The stereoselective synthesis of truxillic bis-amino esters from polyfunctional oxazolones is reported. The reaction of 4-((Z)-arylidene)-2-(E)-styryl-5(4H)-oxazolones 2 with Pd(OAc)2 resulted in ortho-palladation and the formation of a dinuclear open ...

Vagal nerve stimulation improves survival in oxazolone-induced colitis.

, 2018
(A) Wild type BALB/c mice were sensitized by epicutaneous application of 3% oxazolone at a dilution of 4:1 in a mixture of acetone and olive oil (100μl) on day 0, followed by VNS or sham treatment and intracolonic administration of 1% oxazolone dissolved

Merocyanines Derived from Oxazolone

, 1970
Merocyanines, derived from different 2-aryl oxazolone as the acidic nuclei and various basic nuclei like 2-methyl 4-phenyl thiazola, 2-methyl benzothiazole, quinoline-2, quinoline-4 and alpha-picoline have been studied with a view to examining the effect of different substituents present at the position-2 of the oxazolone nucleus on the absorption and ...
