Treatment of N-tosyl-1-aryl-1,2,3,4-tetrahydro-isoquinolines or N-tosyl-1-aryl-1, 2,3,4-tetrahydro-beta-carbolines with a strong base such as NaOH or KOH at 70 degrees C in dimethylsulfoxide (DMSO) produced 1-aryl-3,4-dihydroisoquinolines or 1-aryl-3,4-dihydro-beta-carbolines in good yields via mild and regiospecific beta-eliminations. A dramatic solvent effect was observed, DMSO was crucial for the reactions. The temperature is also crucial for the reactions and should be kept between 60 and 80 degrees C.

Efficient and Practical One-Pot Conversions of N-Tosyltetrahydroisoquinolines into Isoquinolines and of N-Tosyltetrahydro-β-carbolines into β-Carbolines through Tandem β-Elimination and Aromatization
An efficient, practical, and general method for conversions of N-tosyltetrahydroisoquinolines (N-tosyl-THIQs) into isoquinolines and of N-tosyltetrahydro-β-carbolines (N-tosyl-THBCs) into β-carbolines is described. Treatment of N-tosyl-THIQs or N-tosyl-THBCs with base in dimethyl sulfoxide afforded dihydroisoquinolines or dihydro-β-carbolines as intermediates, and these were then oxidized in situ by

ground for the discovery of antimalarial agents (e.g., MMV008138 (1) and cipargamin (2)). Similarity searching of a publicly disclosed collection of antimalarial hits for molecules resembling 1 drew our attention to N2-acyl tetrahydro-β-carboline GNF-Pf-5009 ((±)-3b). Compound purchase, “analog by catalog”, and independent synthesis of hits indicated the benzofuran-2-yl amide portion was required for
四氢-β-咔啉支架已被证明为发现抗疟药物(例如,MMV008138 ( 1 ) 和西帕加明 ( 2 ))提供了肥沃的土壤。对公开披露的类似1的抗疟药物命中集合进行相似性搜索,引起我们对 N2-酰基四氢-β-咔啉 GNF-Pf-5009 ((±) -3b ) 的关注。化合物购买、“按目录模拟”以及命中的独立合成表明,苯并呋喃-2-基酰胺部分是体外对抗恶性疟原虫的功效所必需的。纯对映体的制备证明了( R ) -3b的药理学优越性。 D 环和 F 环取代变体以及苯并呋喃电子等排体的合成和评估表明了清晰的构效关系。最终在伯氏疟原虫感染的小鼠中测试了( R ) -3b ;不利的理化性质可能是缺乏口服功效的原因。
