通过Petasis borono-Mannich反应的一种变体,可以从芳基硼酸,含水乙二醛和1,2-氨基乙醇轻松制备2-羟基-3-芳基吗啉。我们现在表明,可以通过用甲磺酸酐和三乙胺处理将2-羟基-3-芳基吗啉脱氧为3-芳基吗啉,以提供中间体3,4-二氢-2 H -1,4-恶嗪,然后与用三乙酰氧基硼氢化盐和乙酸制得3-芳基吗啉。该反应序列由容易获得的起始材料(1,2-氨基乙醇,芳基硼酸和乙二醛)组成的三步“两锅”制备3-芳基吗啉,具有优异的官能团耐受性和规模适应性。

or pharmaceutically acceptable salts, solvates or derivatives thereof, and to processes for the preparation thereof, intermediates used in their preparation of, compositions containing them and the uses of such derivatives. The compounds of the present invention bind to the enzyme reverse transcriptase and are modulators, especially inhibitors thereof. As such, the compounds of the present invention are useful in the treatment of a variety of disorders including those in which the inhibition of reverse transcriptase is implicated. Disorders of interest include those caused by Human Immunodificiency Virus (HIV) and genetically related retroviruses, such as Acquired Immune Deficiency Syndrome (AIDS).
