Synthesis and photooxidation of furylthymines; chemiexcitation model studies
نویسنده
چکیده
A method for the synthesis of 1-(5-methyl-2-furoyl)thymine (7) and 1-(5-methyl-2-furyl)thymine (8) is described. Trimethylsilyliodide catalysed addition of 5-methyl-2,4-bis(trimethylsilyloxy)pyrimidine (9) to 2-methyl-2,5-dihydro-2,5-dimethoxyfuran yielded the new thymine derivative 13. Photooxidations of 7 and 8 gave not the expected addition products but furan endoperoxides and hydroperoxides and the novel rearrangement product 1-(3-keto-1-butenyl)thymine.

Chemiluminescence molecular probe with intrinsic auto-inductive amplification: incorporation of chemiexcitation in a quinone-methide elimination.
A new signal amplification system with an auto-inductive mode of action and distinct chemiluminescence output was developed. The system is composed of a unique structural motif that combines a chemiexcitation mechanism with a quinone-methide elimination into a signal building block. As demonstrated with a probe designed to detect fluoride, an auto-inductive chemiluminescence signal amplificatio...

متن کاملDirect synthesis of α-bromoketones from alkylarenes by aerobic visible light photooxidation.
The direct synthesis of α-bromoketones from alkylarenes by aerobic photooxidation with hydrobromic acid is reported. The key success for this direct oxidative reaction is due to control of bromination with acetic acid and ethanol, which are generated in situ by solvolysis of ethyl acetate in the course of the reaction.
