A comparative study on the fragmentation of a series of 5-substituted furfurals (X = H, CH3, Cl, Br, I, NO2, COOCH3, COOH) was made. Depending on the nature of the substituent, 2 main pathways of fragmentation were observed One of them starts with the fragmentation of the aldehyde group (X = H, CH3, Cl, Br, I). The other starts with the fragmentation of substituents (X = NO2, COOCH3, COOH). The spectra are discussed on the basis of these 2 fragmentation pathways.

An efficient and versatile one-pot synthesis of 3,6a-epoxyisoindoles annelated with oxazine, oxazole, thiazine, thiazole, pyrimidine fragments and with their benzoannelated analogs is presented. The method is based on tandem N-acylation/intramol. cycloaddition (the intramol. Diels-Alder reaction of furan, IMDAF) reaction between α,β-unsaturated acid anhydrides and α-furyl substituted azaheterocycles. The latter can be easily prepared by condensation of diverse furfurals and 1,2- or 1,3-N,X-binucleophiles (aminoalcs., aminothiols, diamines). The observed IMDAF reaction is stereoselective: exo-adducts are formed exclusively with large prevalence of one of the diastereoisomers. In most cases, the condensation/N-acylation/IMDAF reaction sequence may be carried out via a one-pot domino protocol. The scope and limitations of the proposed approach are thoroughly investigated. The obtained Diels-Alder adducts are attractive and useful substrates for further transformations. Fused isoindoles can be prepared from them in one-step by aromatization of the 7-oxabicyclo[2.2.1]heptene ring. Other transformations, including halogenation, ring cleavage, and Wagner-Meerwein skeletal rearrangement, are also demonstrated. The spatial structures of the obtained compounds have been established by X-ray diffraction analyses.

Let’s take a look at the latest research on this compound (cas:2689-65-8).

A general method is suggested for the synthesis of 4-heteroaryl- and 4-alkynyl-3-Ph sydnones by palladium(0)-catalyzed cross-coupling of 5-oxido-3-phenyl-1,2,3-oxadiazol-3-ium-4-ylcopper (I, R = Cu) with heteroaryl iodides and alkynyl bromides. Thus, I (R = H) was treated sequentially with BuLi, CuBr, and then 2-iodopyridine and Pd(PPh3)4 in THF-C6H6 to give 85% I (R = 2-pyridyl). 5-Oxido-3-phenyl-1,2,3-oxadiazol-3-ium-4-ylzinc chloride (I, R = ZnCl) was synthesized and found to be significantly less reactive than I (R = Cu) and was successfully coupled only with p-iodonitrobenzene and β-bromostyrene.

Hydrogenation of coumarone (I) was carried on by the method and with the catalysts previously described (C. A. 33, 1316.1-2). Under all the conditions used the reaction is accompanied by partial cleavage of the furan ring and the formation of 2-ethylcyclohexanol (II) and β-cyclohexylethyl alc. (III). Passing I with H over Pd deposited on asbestos at 175° formed up to 80% octahydrocoumarone (IV), II and some III. In a similar reaction with the Ni catalyst the yield of II was increased to about 50% and that of IV reduced to 21-2%. The liquid-phase hydrogenation of I in EtOH at 20-50° and atm. pressure in the presence of Pt black and platinized charcoal proceeds analogously, but with the intermediate formation of coumaran (2,3-dihydrobenzofuran).
