Cation amino lipid and synthesis method and application thereof

The invention discloses cation amino lipid and a synthesis method and application thereof. Structure of cation amino lipid is shown as follows. The synthesis method is mild in synthesis reaction condition and high in solvent selectivity, reaction difficulty is lowered greatly, and yield is increased; raw materials are simple and cheap, so that production cost is lowered greatly; more importantly, lipid molecules obtained through screening have the characteristics of high efficiency and low toxicity and can realize good effect in blood serum, so that operation steps of transfection are simplified greatly.
