-
Paragraph 0078-0092, (2021/10/30)
The invention provides a synthetic method of 2, 5-pyrrolidine dimethyl carbinol and derivatives thereof, and belongs to the field of organic synthesis. The synthesis method of 2, 5-pyrrolidine dimethyl carbinol is characterized in that a reaction equation is shown in the specification; in the formula, PG1 is selected from any one of H, benzyl, carbobenzoxy, triphenylmethyl or p-methoxybenzyl, and Cat. is a hydrogenation catalyst. The method comprises the following reaction step that: step 1, a compound 1, the hydrogenation catalyst and H2 contact with one another to obtain a compound 2. According to the method, 2, 5-dicarboxaldehyde pyrrole is selected as a reaction starting raw material, and the specific hydrogenation catalyst is selected, so that the 2, 5-pyrrolidine dimethyl carbinol can be obtained in a one-step reduction and high-yield manner, and the production cost is effectively reduced.
