Preparation method of hydroxymethyl-substituted aromatic heterocyclic compound
-
Paragraph 0049-0055, (2020/08/02)
The invention provides a preparation method of a hydroxymethyl-substituted aromatic heterocyclic compound, which comprises the following steps: in the presence of protective gas, dissolving aromatic heterocarboxylic acid in an aprotic solvent, adding a reducing agent in an ice bath, performing heating to room temperature, and performing reacting to obtain the hydroxymethyl-substituted aromatic heterocyclic compound. The yield of the hydroxymethyl substituted aromatic heterocyclic compound is 93% or above, the raw materials are cheap and easy to obtain, the method is simple, efficient and mildin reaction condition, and the defect that dangerous chemicals such as sodium borohydride which are prone to explosion are used in a conventional synthesis method can be overcome.

A reactivity study, aided by NMR spectroscopy, allowed a mechanistic rationale to be postulated for the palladium-catalyzed regioselective coupling of arylboronic acid (and arylstannane where feasible) at the position next to the sulfur atom in functional

The straightforward methodology for the construction of chiral arene-fused-piperidine motifs using a highly enantioselective addition of 2-trityloxymethylaryllithiums to cyclic and acyclic nitroalkenes has been developed. The versatility of the process wa
