Tandem Reduction, Ammonolysis, Condensation, and Deamination Reaction for Synthesis of Benzothiadiazines and 1-(Phenylsulfonyl)-1<i>H</i>-benzimidazoles
A novel route for a SnCl2-promoted tandem reduction, ammonolysis, condensation, and deamination reaction which uses nitrile and 2-nitro-N-phenylbenzenesulfonamide/N-(2-nitrophenyl)benzenesulfonamide to synthesize derivatives of benzothiadiazine/1-(phenylsulfonyl)-1H-benzimidazole has been developed. The method features convenient operation and good functional group tolerance. In addition, it employs
SnCl 2促进串联还原、氨解、缩合和脱氨反应的新路线以腈和2-硝基-N-苯基苯磺酰胺/ N- (2-硝基苯基)苯磺酰胺合成苯并噻二嗪/1-(苯磺酰基)衍生物开发了-1H-苯并咪唑。该方法操作方便,官能团耐受性好。此外,它采用不敏感且廉价的 SnCl 2 / i -PrOH 作为反应试剂,为合成重要的药学靶标提供了直接途径。
Design, synthesis and biological evaluation of novel benzothiadiazine derivatives as potent PI3Kδ-selective inhibitors for treating B-cell-mediated malignancies
A series of 24 benzothiadiazine derivatives with structural novelty were designed, synthesized and biologicallyevaluated as PI3Kδ-selective inhibitors. As a consequence of the structure-activity relationship (SAR) study, compounds 63 and 71 were identified with single-digit nanomolar IC50 values against PI3Kδ and submicromolar GI50 values against human malignant B-cell line SU-DHL-6. Furthermore,

A direct method for the allylation of 2-nitrosulfonamides is described and exemplified. The mild and flexible conditions used as well as the ease to remove the 2-nitrosulfonamide group are compatible with a large set of chemical moieties.
