Described are methods of making pyranoindazole compounds comprising converting a pyranoindazole diol mixture to form a diastereomeric mixture of cyclic pyranoindazole carbonates, separating the mixture of cyclic pyranoindazole carbonates, and converting at least one of the separated diastereoisomeric cyclic pyranoindazole carbonates by hydrogenolysis. Also disclosed are intermediates useful for such and additional methods.
本文描述了制备吡喃吲唑化合物的方法,包括将吡喃吲唑二醇混合物转化为环状吡喃吲唑碳酸酯的对映体混合物,分离环状吡喃吲唑碳酸酯混合物,并通过氢解反应转化至少一种分离的对映体环状吡喃吲唑碳酸酯。此外还公开了用于这种和其他方法的中间体。
