I have Syrian passport and a visa to China. I'm currently in Nanjing and want to go to Macau.Can I?

You can go to Macau and apply for Macau visa on arrival. However, it is hard to say that you will get it. Please try your luck! Take your valid passport, the China visa on your passport, the round-trip flight tickets and hotel booking in Macau, the documents can increase the chance of getting a Macau visa.
