Heterocyclic Building Blocks-Tetrahydroisoquinoline

Reference of 1745-07-9, New Advances in Chemical Research, May 2021. Chemistry is the experimental science by definition. We want to make observations to prove hypothesis.

Coclaurine N-methyltransferase from Coptis japonica catalyzes the N-methylation of coclaurine as well as simple tetrahydroisoquinoline. We examined the possibility of converting 6,7-dimethoxy-1,2,3,4- tetrahydroisoquinoline into its N-methylated product using transgenic Escherichia coli, which expressed recombinant coclaurine N-methyltransferase, without the addition of a methyl-group donor. Transgenic E. coli successfully N-methylated the substrate added to the medium and excreted the product. Limitation of bioconversion by the supply of methyl-group donor is discussed.

Future efforts will undeniably focus on the diversification of the new catalytic transformations. These may comprise an expansion of the substrate scope from aromatic and heteroaromatic compounds to other hydrocarbons. Keep reading other articles of 1745-07-9. Reference of 1745-07-9

Related Products of 166591-85-1, 166591-85-1, Name is 2-(tert-Butoxycarbonyl)-1,2,3,4-tetrahydroisoquinoline-1-carboxylic acid, molecular formula is C15H19NO4. In a Article，once mentioned of 166591-85-1

An irreversible hydrolysis reaction of allyl esters (1) into carboxylic acids (2) and propanal (3) was achieved with a ruthenium/palladium (Ru/Pd) dual catalyst system. The optimized catalysts consists of a 1:1:1 mixture of (cyclopentadienyl)tris(acetonitrile)ruthenium hexafluorophosphate {[RuCp(MeCN)3] PF6}, bis(acetonitrile)palladium dichloride [PdCl2(MeCN)2] and 1,6-bis(diphenylphosphanyl)hexane (DPPHex). The reaction proceeds via isomerization of allyl esters to 1-propenyl esters and hydrolysis of them to give 2 and 3. The first isomerization step was virtually catalyzed by the Ru components and the second hydrolysis step was mainly catalyzed by the Pd components. The optimized bidentate phosphine (DPPHex) which has long alkylene chain effectively generates two vacant sites on the Ru centers by bridging coordination. When a chelating bidentate phosphine such as DPPE was employed, only one vacant site remained on the Ru center and resulted in a low activity. This chelating Ru complex of DPPE formed even in the presence of 2 equivalents of Ru or additional 1 equivalent of Pd. These differences in coordination behaviour between DPPHex and 1,2- bis(diphenylphosphanyl)ethane (DPPE) cause the differences of the catalytic activity in the first step. The phosphine coordination to Pd center slightly decreases the activity of second hydrolysis step but which was compensated by the increasing of the stability of Pd. On the whole, the optimized Ru/Pd dual catalyst system exhibited good performances on the irreversible hydrolysis of allyl esters.

Visible-light-induced, eosin Y catalyzed aerobic oxidative alpha-C(sp3)-H thiocyanation of tertiary amines is reported. The reaction proceeds through visible-light-induced in situ generation of the iminium ion followed by attack of -SCN nucleophile. This is the first example of visible-light-initiated formation of C(sp3)-S bond employing organo-photoredox catalysis. Mild reaction conditions and use of air and visible light as the greenest and sustainable reagents at room temperature are the salient features of the protocol.

The hydrogenation of beta-keto esters containing a furan unit at the conjugated position to the beta-carbonyl group was carried out over a chiral heterogeneous catalyst, tartaric acid-modified Raney nickel. The hydrogenation first proceeds at the carbonyl to give optically active alcohols, but a simple substrate undergoes further hydrogenation of the furan part to produce a diastereomeric mixture of alcohols having a tetrahydrofuran moiety. This over-reduction was efficiently suppressed by substitutions of a substituent at the furan part. The optical yield at the hydroxy group is in the range of 40-90%.
