Contrary to a report that the reaction of benzo[b]cyclohepta[e][1,4]oxazine 1 with α,γ-diamine 2b produces 1,2,3,4-tetrahydrocyclohepta[b][1,4]diazepine 4, the product was found to be 2-phenyl-3,4,5,6-tetrahydropyrimidine 5b and is peculiar to the reaction of 1 with α,γ-diamines 2 as well as β-aminamide 7.
与有关苯并[ b ]环庚[[ e ] [1,4]恶嗪1与α,γ-二胺2b反应的报告相反,生成1,2,3,4-四氢环庚[ b ] [1,4]二氮杂4,发现该产物是2-苯基-3,4,5,6-四氢嘧啶5b,是1与α,γ-二胺2和β-氨基酰胺7的反应所特有的。
