Abstract

The invention discloses a method for efficiently producing melatonin, relates to the technical field of melatonin synthesis, and aims to solve the problems that purity and an extraction rate of melatonin are relatively low and preparation cost is relatively high in the prior art. According to the method, 5-methoxy indole is taken as 100% of a raw material, carbonyl chloride accounts for 98% of theraw material, ammonium hydroxide accounts for 57% of a generation compound, and lithium aluminum hydride accounts for 80% of the generated compound. The 5-methoxy indole (1) is taken as a raw material, and a carbonyl chloride reaction solvent is added to acylate the 5-methoxy indole, so that a reaction is carried out to generate a compound (2); the generated compound (2) is stranded, and then anammonium hydroxide solvent is mixed with the generated compound (2) according to a certain usage amount to generate a compound (3); and after the compound (3) is generated, a lithium aluminum hydridereagent is added to carry out a reduction reaction on the compound (3) to generate a compound (4).

Description

technical field [0001] The invention relates to the technical field of melatonin synthesis, in particular to a method for efficiently producing melatonin. Background technique [0002] Melatonin is an amine hormone produced by the pineal gland in mammals and humans, which makes a type of melanin-producing cell glow, hence the name melatonin. It exists in many organisms from algae to humans, and the content level changes with the time of day. Melatonin is the first biologically active substance discovered in the pineal gland. When mammals are in the dark, melatonin The secretion activity is immediately strengthened; when it is turned into a bright environment, the secretion stops. The rhythm of melatonin secretion can be measured from urine as the light changes. Other factors such as sleep, diet, mental state, and stress also play a role. Injection of melatonin into the hypothalamus can inhibit the secretion of gonadotropins, but it has also been observed that melatonin ca...
