We provide an account of synthetic strategies aimed at the efficient preparation of 4-amino-4-methyltetrahydro-2H-thiopyran 1,1-dioxide (3), an important cyclic sulfone building block for medicinal chemistry. A practical and scalable protocol has been developed that readily gives access to the title compound from commercially available and inexpensive starting materials. In addition, this novel approach
我们提供了旨在有效制备4-氨基-4-甲基四氢-2 H-硫代吡喃1,1-二氧化物(3)(一种重要的药用化学环砜构件)的合成策略。已经开发出一种实用且可扩展的方案,该方案可容易地从市售和廉价的起始原料中获得标题化合物。另外,这种新颖的方法使得能够合成各种相关的4,4-二取代的环砜衍生物,这些衍生物用作药物发现的有价值的结构基序。
