New discoveries in chemical research and development in 2021. In heterogeneous catalysis, the catalyst is in a different phase from the reactants. Safety of 6,7-Dimethoxy-1,2,3,4-tetrahydroisoquinoline, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 1745-07-9, name is 6,7-Dimethoxy-1,2,3,4-tetrahydroisoquinoline. In an article，Which mentioned a new discovery about 1745-07-9
When the products of a Strecker reaction of 1,2,3,4-tetrahydroisoquinolines with aromatic aldehydes are quaternized with alkyl triflates and subsequently treated with base, a ring expansion to 6,7,8,13-tetrahydro-5H-dibenzo[c,f] azonine-5-carbonitriles takes place. The nine-membered cyclic products can be obtained in good yields (78-89%) in a process involving the [1,4]-sigmatropic rearrangement of a nitrile-stabilized ammonium ylide. The reaction sequence provides a new, simple, and efficient method for the synthesis of these unusual N-heterocycles.
