Concise Synthesis of Dictyoquinazol A via a Dimerisation–Cyclocondensation Sequence
摘要:
A two-step total synthesis of the neuroprotective alkaloid, dictyoquinazol A, has been achieved. The brevity of this synthesis was enabled by exploiting the hidden symmetry of the target molecule. Several structural analogues were also prepared using a similar strategy. These results provide a platform for future structure-activity relationship studies in the quest for a novel treatment for stroke.

A convenient route for efficient conversion of unprotected anthranilic acids into the corresponding N-(2-aminoarylacyl)benzotrazoles is described. N-(2-Aminoarylacyl)benzotrazoles have been successfully used to synthesize primary, secondary and tertiaryanthranilamides in high yields (71-96%).
