    摘要: 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.
