metal catalyzed amidations remains a challenge. Here, a manganese(I)-catalyzed method for the direct synthesis of amides from a various number of esters and amines is reported with unprecedented substrate scope using a low catalyst loading. A wide range of aromatic, aliphatic, and heterocyclic esters, even in fattyacid esters, reacted with a diverse range of primary aryl amines, primary alkyl amines

this property. The most active derivative, N-[3-[(4-amino-6, 7-dimethoxy-2-quinazolinyl)methylamino]propyl]tetrahydro-2-furancarbo xamide hydrochloride, alfuzosin (12), showed high selectivity for peripheral alpha 1-postjunctional adrenoceptors. At equiactive antihypertensive doses, its effect on the pressor response to postural changes in conscious dog was less marked than that shown by prazosin. In the
合成了一系列的N2-[(酰基氨基)烷基] -6,7-二甲氧基-2,4-喹唑啉二胺作为潜在的α1-肾上腺素受体拮抗剂。当以10 mg / kg po自发性高血压大鼠给药时,许多丙烷二胺衍生物显示出良好的降压活性,而乙二胺衍生物尽管在结构上与哌唑嗪密切相关,却缺乏该特性。活性最高的衍生物N- [3-[(4-氨基-6,7-二甲氧基-2-喹唑啉基)甲基氨基]丙基]四氢-2-呋喃甲酰胺x盐酸盐阿夫唑嗪(12)对外围α1具有很高的选择性。 -结后肾上腺素受体。在等剂量的降压剂量下,其对清醒犬体位变化的升压反应的作用不如哌唑嗪所显示。根据这些结果,

are herein reported as new catalysts for the synthesis of aryl amides by catalytic condensation of aromatic carboxylicacids with amines. The developed protocol is both simple and highly efficient over a broad range of substrates. This method thus represents an attractive approach for the use of diboron catalysts in the synthesis of amides without having to resort to stoichiometric or additional dehydrating
