Iridium catalyst for chiral amine synthesis

Excellent functional group tolerance, capable of reacting with a wide range of substrates! Chiral amines can be obtained directly from ketones! Furthermore, the reaction can also be performed in a one-pot manner!

At Kanto Chemical, we have developed and sold practical reductive amination iridium catalysts that can synthesize amines under mild conditions, and we have now developed a new asymmetric reductive amination catalyst. In particular, in the reductive amination reaction combined with amino alcohols as asymmetric auxiliaries, it has become possible to easily synthesize optically active amines, which have been difficult to synthesize asymmetrically until now. We are pleased to announce the addition of the PSA18 series, which has high reactivity with linear ketone substrates, to our product lineup. We encourage you to utilize it in product development and research. 【Features】 ■ High performance High catalytic activity, high stereoselectivity, high functional group selectivity ■ Short reaction process No need for isolation of imines; reactions can be performed in one pot up to deprotection ■ Easy operability No need for hydrogen gas or pressure-resistant containers for both reductive amination and deprotection processes For more details, please download the catalog or feel free to contact us.

Asymmetric molecular catalyst

It is a catalyst that takes into consideration both safety and environmental aspects.

■Asymmetric Hydrogenation Catalyst (IPHAN, DMAPEN Catalyst) In asymmetric hydrogenation catalysts, diamin ligands such as DPEN and DAIPEN are commonly used. At Kanto Chemical, we offer asymmetric hydrogenation catalysts (IPHAN, DMAPEN catalysts) that demonstrate high enantioselectivity in the asymmetric hydrogenation of cyclic ketones and amino ketones by changing the diamin ligands to different structures like IPHAN and DMAPEN. ■Asymmetric Phase Transfer Catalyst (DIOXEAZEPINE) The metal-free DIOXEAZEPINE catalyst is expected to be an effective means for the synthesis of optically active pharmaceuticals, as it avoids contamination of the product with metal derived from the catalyst. This catalyst is useful for the synthesis of optically active α-α-dialkyl amino acids. For more details, please download the catalog or feel free to contact us.

Non-uniform hydrogenation catalyst 's-PICA catalyst'

The ketone that had given up on the asymmetric reaction has become an optically active alcohol with high enantioselectivity!

This is a new asymmetric hydrogenation ruthenium catalyst developed in collaboration with Professor Okuma from Hokkaido University, featuring a unique substrate applicability range that has never been seen before. It efficiently converts ketones into optically active alcohols with high efficiency and high enantioselectivity. By selecting the reaction conditions, it is also possible to reduce keto esters to diols. The catalyst is suitable for bulk supply, making it useful for industrial processes. **Features** - Unique substrate applicability range: It hydrogenates bulky multi-substituted ketones, unprotected heteroaromatic ketones, and keto esters with high efficiency and high enantioselectivity, which conventional catalysts could not efficiently react with. - Proven performance at kg scale: There is a track record of asymmetric hydrogenation reactions at tens of kg scale. Reactions are also possible with a substrate/catalyst molar ratio (S/C) of over 10,000. For more details, please download the catalog or feel free to contact us.

Improved asymmetric reduction catalyst & triflate catalyst

It can be used for hydrogen transfer asymmetric reduction reactions and asymmetric hydrogenation reactions of ketones.

■Improved Asymmetric Reduction Catalyst Asymmetric ruthenium complexes with optically active tosyl diamines as ligands are very useful as asymmetric reduction catalysts for ketones; however, sufficient enantioselectivity may not be achieved for bulky substrates. At Kanto Chemical, we offer an improved asymmetric reduction catalyst with modified sulfonyl groups that exhibits high enantioselectivity for bulky substrates. ■Triflate Catalyst By introducing dissociative anionic ligands into hydrogen transfer-type asymmetric ruthenium catalysts with arene ligands and tosyl diamine ligands, hydrogen is activated, allowing for more efficient asymmetric hydrogenation reactions of ketones compared to hydrogen transfer-type asymmetric reduction catalysts. The triflate catalyst does not contain strong bases, so the reaction proceeds under neutral to weakly acidic conditions. Therefore, it is useful for the asymmetric hydrogenation of unstable cyclic ketones, phenacyl chloride, α-hydroxyacetophenone, and other compounds under basic conditions. For more details, please download the catalog or feel free to contact us.
