Summary: A paper has been published on the asymmetric synthesis of alogliptin, a type 2 diabetes drug that was developed during the Takeda era. An efficient and eco-friendly synthesis was achieved by synthesizing an optically active amine from an inexpensive nicotinic acid derivative as raw material using an asymmetric hydrogenation reaction, followed by a condensation reaction with the corresponding parent core structure and finally obtaining alogliptin through use of a sophisticated Hofmann rearrangement.
The research started during the Takeda Pharmaceutical Company era, but the key asymmetric synthesis technology has been transferred to SPERA PHARMA. We will continue to utilize the technology and the vast experience, to support customers in solving their problems and contribute to the swift creation of pharmaceutical products.
