Studies of seven-membered heterocyclic compounds containing nitrogen. IX. The synthesis of 5-ethoxycarbonyl-1-azacycloheptan-4-one and its derivatives was written by Moriya, Tamon;Oki, Toichi;Yamaguchi, Seiki;Morosawa, Shiro;Yokoo, Akira. And the article was included in Bulletin of the Chemical Society of Japan in 1968.Application of 19673-14-4 The following contents are mentioned in the article:
Ring expansion of 1-benzyl-1-azacyclohexan-4-one and 1-ethoxycarbonyl-1-azacyclohexan-4-one with Et diazoacetate in the presence of BF3.Et2O gave I (R = PhCH2, R1 = CO2Et, R2 = H) (II) and I (R = R1 = CO2Et, R2 = H), resp. These compounds gave pyrazole or pyrazolone type derivatives when treated with N2H4 or H2NNHPh. Methylation of II gave I (R = PhCH2, R1 = CO2Et, R2 = Me), which was converted to I (R = CO2Et, R1 = Me, R2 = H) by decarboxylation, debenzylation, and ethoxycarbonylation. This study involved multiple reactions and reactants, such as Ethyl 5-oxoazepane-4-carboxylate hydrochloride (cas: 19673-14-4Application of 19673-14-4).
Ethyl 5-oxoazepane-4-carboxylate hydrochloride (cas: 19673-14-4) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Application of 19673-14-4
