A Novel Class of P−O Monophosphite Ligands Derived from d-Mannitol: Broad Applications in Highly Enantioselective Rh-Catalyzed Hydrogenations

The Journal of Organic Chemistry (2004)

Hanmin Huang Zhuo Zheng Huili Luo Changmin Bai Xinquan Hu

We report on a new class of P-O monophosphite ligands (designated 3a-k) with a double six-membered-ring backbone onto which are attached additional groups and on applications of their Rh complexes in the hydrogenation of enamides, alpha-dehydroamino acid esters, dimethyl itaconate, and beta-(acylamino)acrylates. Our results demonstrate that the Rh complexes with ligands 3a-k exhibit high enantioselectivity and reactivity in asymmetric hydrogenation reactions. An ee value of up to 98.0% was obtained for the hydrogenation of alpha-dehydroamino acid esters, and the ee values were all over 99% for the other three types of substrate, with a turnover number of up to 5000.

Palladium‐Catalyzed Ring‐Closing Aminoalkylative Amination of Unactivated Aminoenynes

Angewandte Chemie International Edition (2022)

Suchen Zou Bangkui Yu Hanmin Huang

An efficient strategy for preventing the β-hydride elimination of alkylpalladium species by ligation of the palladium with adjacent amino-group was developed, which enabled a novel palladium-catalyzed ring-closing aminoalkylative amination of unactivated aminoenynes. The reaction is amenable to aminals, as well as aliphatic aldehydes with secondary amines, which provides straightforward access to structurally diverse exocyclic allenic amines bearing 5 to 12-membered N-heterocycles. With chiral phosphoramidite-ligated palladium complex as the catalyst, an enantioselective variant was achieved with up to 93 % ee. Simultaneously, synthetic transformations of the chiral products were also conducted to afford structurally unique spirodiamines including one pharmaceutically active molecule via axial-to-central chirality transfer.

New urbanism and sustainable city——Implications for china

Fujian Architecture & Construction (2013)

Hanmin Huang

In the 21st century,sustainable city will be the main direction of urban development. To solve various problems in the rapid urban development,planners summed up methods and theories during practice,one of them is the New Urbanism. This paper describes the theory of the New Urbanism and its concept of sustainable development to provide benificial inspiration about how to build sustainable cities in China combining with China's conditions.

Palladium-Catalyzed Intramolecular Hydroaminocarbonylation to Lactams: Additive-Free Protocol Initiated by Palladium Hydride

ACS Catalysis (2016)

Yue Hu Zhiqiang Shen Hanmin Huang

A palladium-catalyzed intramolecular hydroaminocarbonylation of 2-vinylbenzylamines in the absence of acidic or any other additives was realized via rational designing the catalytic system on the basis of mechanistic studies, which allows for the synthesis of a variety of six-membered lactams in good to excellent yields with high regioselectivity. The postulated palladium-hydride intermediate for initiating the hydroaminocarbonylation has been identified and directly used as a catalyst for the reaction. Further kinetic studies illustrated that the reaction rate is negative first-order-dependent on the substrate concentration with palladium hydride as a catalyst.
