approach towards the production of diverse sets of diaminopyrimidines through sequential SNAr reactions is reported. The readily prepared 2-chloro-4-tetrafluorophenoxypyrymidine reacts regioselectively with amines at the C-2 position. The tetrafluorophenoxy at C-4 can then be replaced with amines in a second SNAr to afford easy access to a different and complementary set of diaminopyrimidines. The broad
通过顺序对朝生产不同套二氨基嘧啶的新方法Ñ报道的Ar反应。容易制备的2-氯-4-四氟苯氧基嘧啶在C-2位置与胺发生区域选择性反应。然后可以在第二个S N Ar中将C-4处的四氟苯氧基替换为胺,以轻松获得一组不同且互补的二氨基嘧啶。该“ C-2然后C-4”两步序列的广泛用途已在一系列芳族和脂族胺中得到证实。

Dimorpholinopyrimidines are useful for inhibiting growth or proliferation of hamartoma tumor cells. Because the Dimorpholinopyrimidines inhibit the growth and proliferation of hamartoma tumor cells they are also useful in treating PTEN hamartoma tumor syndromes. The therapeutic and prophylactic treatments provided by this invention are practiced by administering to a patient in need thereof an amount of a compound of dimorpholinopyrimidine derivative that is effective to inhibit growth or proliferation of the hamartoma tumor cells.
A mild and highly efficient catalytic amination procedure for chloroheteroarenes at ambient temperatureusing the Pd/PTABScatalyticsystem is reported. The protocol is selective for the amination of chloroheteroarenesusing secondary amines such as piperidine, pyrrolidine, and several others. The exceptional mildness of the developed protocol is beneficial for the synthesis of a crucial Buparlisib

uncertainties in the network parameters. From considering the steps of the reaction network in isolation, the kinetic parameter uncertainties are reduced by 50%, with less than 5 g of the dichloropyrimidine substrate consumed over all experiments. We conclude that isolating pathways in the multistep reaction network is important to minimizing uncertainty for low sensitivity rate parameters.

Coupling reaction between electron-rich 2-morpholino-4(3H)-pyrimidinone and nucleophilic side chains of several natural α-amino acids promoted by phosphonium salt has been developed to prepare new optically active pyrimidin-4-yl amino acids. The best results were obtained using a two-step method through the easily available benzotriazolyl-1-oxy intermediate. A detailed optimization study of this reaction is discussed.
