Chemistry graduates have much scope to use their knowledge in a range of research sectors, including roles within chemical engineering, chemical and related industries, healthcare and more. Computed Properties of https://www.ambeed.com/products/10323-20-3.html10323-20-3, Name is D-Arabinose, SMILES is O=C[C@@H](O)[C@H](O)[C@H](O)CO, belongs to dioxole compound. In a article, author is ADAM, W, introduce new discover of the category.

The low temperature photooxygenation of the furocoumarins 1a-e, the naphthofurans 1f-h, and the furoquinoline 1i afforded the corresponding dioxetanes 2 in good yields, except the linearly annulated naphthofuran 1f, which led exclusively to the allylic hydroperoxide 5f by ene reaction with singlet oxygen. The dioxetanes 2 were rigorously purified by means of low temperature silica gel chromatography and fully characterized. Thermolysis of the furocoumarin dioxetanes 2a-e led to the expected cleavage products 3a-e (acetyloxy- and acetyl-substituted coumarins), while the naphtho- and quinolinofuran dioxetanes 2g-i gave in addition to the cleavage products 3g-i also the spiroepoxides 4g-i. Intramolecular electron transfer from the aromatic moiety to the dioxetane ring, with subsequent cyclization of the radical-ion species and fragmentation is postulated as mechanism for the formation of this novel rearrangement product of dioxetanes. On heating in chloroform the spiroepoxides 4g,h rearranged into the 1,3-dioxole 6g, but heating of 4g in methanol gave the dioxine 7g by trapping of the dipolar intermediate. – The furocoumarin dioxetanes 2a,c,d showed high mutagenic activity in the Salmonella typhimurium strain TA 100 but not in the strain TA 2638. The naphtho- and quinolinofuran dioxetanes 2h,i and the spiroepoxides 4g,h were nonmutagenic in the TA 100 strain. Epoxide-like DNA damage appears to be responsible for the mutagenicity of the furocoumarin dioxetanes 2a,c,d.
