Phosphorylation and cyclophosphorylation of 1,4-diacetoxyanthracene and dianthrone
摘要:
Phosphorylation and cyclophosphorylation of 1,4-dihydroxyanthracene and dianthrone by hexaalkylphosphorous triamides in pyridine was effected for the first time. The phosphorylation rate is found depending on the type of the alkyl fragment in the amido group of the phosphorylating agent. Cyclic phosphoramidites derived from anthracene were prepared both by molecular assembling and direct cyclophosphorylation. Thio and oxo derivatives of these cyclic compounds were obtained. Dianthrone derivatives undergo intramolecular cycloaddition at only one anthracene fragment to form an interesting bulky structure containing the phospholane ring.
