An approach to 5-substituted 6,7,8,9-tetrahydro-5H-pyrido[3,2-c]azepines via the cyclization of 1-(2-(3-azidopropyl)pyridin-3-yl)alkanones under Staudinger-aza-Wittig reaction conditions is described (I → II using PMe3; R = Ph, 4-FC6H4, i-Pr). The overall reaction sequence includes eight steps and allows for the preparation of gram quantities of the title products. In some cases, the formation of 5,7,8,9-tetrahydrooxepino[4,3-b]pyridine derivatives was observed The experimental process involved the reaction of 2-Bromonicotinaldehyde(cas: 128071-75-0Recommanded Product: 128071-75-0)
2-Bromonicotinaldehyde(cas: 128071-75-0) belongs to pyridine. The basicity and metallophilic high donor number of these π-deficient systems has long favored them as ligands in metal catalysis. The last decade saw pyridine assume a stronger role as functional group for directed C–H oxidation/activation.Recommanded Product: 128071-75-0
