Abstract

The invention relates to a synthetic method for a carbonyl steroid-containing compound derivatization reagent, and belongs to the technical field of chemical synthesis. The synthesis method comprisesthe following steps of: firstly, reacting 1, 3-dibromopropane with N-hydroxyphthalimide to synthesize 2- (3-bromopropoxy) isoindoline -1, 3-diketone; preparing 3-((1,3-dioxo-2-isoindolyl)-oxy)-N, N, N-trimethylpropylammonium bromide by utilizing 2-(3-bromopropoxy) isoindoline -1, 3-diketone; and finally, carrying out hydrazinolysis on the 3-((1, 3-dioxo-2-isoindoline)-oxy)-N, N, N-trimethylpropylammonium bromide. The synthesis method is low in cost, simple in step and high in yield; the carbonyl-containing steroid compound can be derivatized; a permanently charged group N+Me3 is introduced into the carbonyl-containing steroid compound, and the detection sensitivity of the carbonyl-containing steroid compound in ESIMS / MS is improved.

Description

technical field [0001] The invention belongs to the technical field of chemical synthesis, and more specifically relates to a synthesis method for a derivatization reagent of a carbonyl-containing steroid compound. Background technique [0002] Carbonyl-containing steroids are a class of non-polar compounds that are secreted by the endocrine system and regulate metabolic processes, and have important physiological functions. Due to the low concentration of carbonyl-containing steroids in biological samples, poor ionization efficiency, and many isomers, their analysis is facing great challenges. At present, the analysis of such compounds often uses the strategy of derivatization, and the introduction of ionizable groups in the molecule can significantly improve its sensitivity. Commonly used derivatization reagents include dansyl chloride (DNS-Cl), picolinic acid (PA), 1-methylimidazole-2-sulfonyl chloride (MLDS), pyridine-3-sulfonyl chloride (PS), (3-dimethyl (aminophenyl)...
