This review summarizes the strategies for the synthesis of star-shaped molecules as well as their specific syntheses.

A new series of poly(tetrahydrobenzimidazo[2,1-b]-quinazolin-1(2H)-ones) was synthesized in good yields using a multicomponent reaction of poly(aldehydes), dimedone, and 2-aminobenzimidazole in DMF under conventional heating as well as under microwave irradiation.

The synthesis of novel star-shaped compounds based on an s-triazine core and linked to different heterocycles as new hybrid molecules through Michael and Hantzsch reactions is reported.
