Synthesize E-type alkenes with high efficiency!
This technology is a method for synthesizing E-alkenes in high yield through the selective reduction of alkynes. In conventional methods, the synthesis of E-alkenes from alkynes had low yield and selectivity, making it difficult to synthesize efficiently. This technology has achieved high-efficiency synthesis of E-alkenes by developing a novel aluminum-based complex. It is a versatile and low-cost synthesis method that does not require hazardous reagents or gases, nor expensive transition metals. Features of the technology: - High yield and high selectivity for synthesizing E-alkenes from internal and terminal alkynes. - Diverse alkene derivatives can be developed starting from the synthesized substituted alkenes. - No need for safety-considerate equipment or buildings; reactions can be conducted using conventional facilities.

basic information
(Technical Content) New Hydroalumination Reaction Using Novel Aluminum Reagents ■ Using complexes of fluoride salts and di-substituted hydride aluminum ■ Synthesis of substituted alkenes - For internal alkynes, E-alkenes are produced with high yield, confirming high E-selectivity. - For terminal alkynes, a different stereoselectivity is observed compared to conventional methods. The bromination of the Al intermediate occurs with stereoselective Br addition. (Application Examples) ■ Versatile Alkene Synthesis Platform - Starting from substituted alkenes (intermediate A) synthesized by this method, it is possible to expand into multiple transformation reactions according to application. *For more details, please download the PDF or feel free to contact us.*
