Synthesis and reactions of 2,3,5,6-tetrahydro-2,5-ethano-3-benzazocin-4(1H)-one and a thieno-extended analog: x-ray structure of 3-methyl-2,3,5,6-tetrahydro-2,5-ethano[1]benzothieno[3,2-d]azocin-4(1H)-one was written by Iddon, Brian;Redhouse, Alan D.;Yat, Patrick N.. And the article was included in Journal of the Chemical Society, Perkin Transactions 1: Organic and Bio-Organic Chemistry (1972-1999) in 1990.Recommanded Product: 6287-82-7 This article mentions the following:
Hexahydromethanobenzocyclooctenone I (X = O) was prepared by condensation of o-xylene-α,α’-diyl dibromide with N-cyclopentylidenepyrrolidine and converted by Beckmann rearrangement of I (X = NOH) into tetrahydroethanobenzazocinone II (R = H). 2,3-Bis(bromomethyl)benzo[b]thiophene was converted similarly into a mixture of tetrahydroethanobenzothienoazocinones III (X1 = NH, X2 = CO; X1 = CO, X2 = NH). II (R = H) was N-methylated and II (R = H, Me) were reduced with LiAlH4 to the saturated products. Conversion of II (R = H) into the corresponding thiolactam with P2S5 followed by alkylation gave an N– or S-alkylated derivative, (e.g., IV, R = Me, Et), depending on the reagent and reaction conditions. The structures of a number of compounds in this work are based on the x-ray anal. of III (X1 = CO, X2 = NMe). In the experiment, the researchers used many compounds, for example, 2,3-Dibromobenzo[b]thiophene (cas: 6287-82-7Recommanded Product: 6287-82-7).
2,3-Dibromobenzo[b]thiophene (cas: 6287-82-7) belongs to benzothiophene derivatives. Benzothiophenes are valuable heterocycles that are widely used in medicines, agrochemicals, and materials science. It is also used in the manufacturing of dyes such as thioindigo.Recommanded Product: 6287-82-7
