【Abstract】 The development of privileged heterocyclic scaffolds isa rapidly emerging subject in medicinal chemistry. Benzodiazepine analogues are considered as privileged structures in medicinal chemistry and often possess a wide range of interesting pharmacological activities.Pyrimidines and pyrimidine- fused compounds are widely studied because of their interesting pharmacolo-gicalactivities. For example, some pyrrolopyrimidines arereported to have antitumor activities, some aminopyridopyrimi-dinesare novel non-nucleoside adenosine kinaseinhibitors, certain furanopyrimidines are potent andselective inhibitors of human cytomegalovirus (HCMV), 4 and 5-substituted furo[2,3-d]pyrimidines exhibit potentinhibitory activity against the growth of tumor cells. Another class of heterocyclic scaffolds with celebrated biological activities in the central nervous system is the benzothienodiazepines. for example, Olanzapine.Recently, we introduced a new methodology for the efficient synthesis of pyrimidine-fused thienodiazepines via Bischler- Napieralski-type and Pictet–Spengler reactions. To expand the scope of these methods and access to new heterocyclic scaffolds, we envisioned that Bischler-Napieralski-type and Pictet–Spengler-like cyclization of 5-Amino-6-chloro-4-N-methyl-thiophene-pyrimidine with an acyl chloride or aldehyde should lead to tricyclic 4-chloro-pyrimido[4,5-b][1,4]thienodiazepines or 4-chloro-5,6-dihy- dropyrimido[4,5-b][1,4]thienodiazepines. The 4-chloro group in 4-chloro-pyrimido[4,5-b][1,4]thienodiazepines can be easily converted to other groups by a substitution reaction with a nucleophile (such as an amine, alcohol, and phenol and so on) .the synthetic strategy provides an efficient way to access to libraries of novel heterocyclic compounds with potential pharmaceutical or biological activities.更多还原
