(R)-(+)-8,9-Dimethoxy-6,10b-dihydro-5H-thiazolo[2,3-a]isoquinolin-3-one 1 has been synthesized from 6,7-dimethoxy-3,4-dihydroisoquinoline and menthyl thioglycolate. Compound 1 was obtained in the enantiomerically pure form (mp 150-153C, [alpha]D +436) by a single crystallization of the crude reaction product (68% e.e.) from 96% ethanol. The absolute 10bR configuration was established by X-ray diffraction. Oxone oxidation of 1 resulted in a configurationally unstable dextrorotatory syn-sulfoxide 2 (mp 173-175C, [alpha]D +62.8).

A highly effective bicycloannulation methodology for the synthesis of berban and yohimban alkaloid systems is described.Three-component coupling reactions of 2,4-pentadienyltin reagents with C=N bonds and alpha,beta-unsaturated acyl chlorides furnish bicycloannulated products in a one-pot operation.For example, the reactions of 2,4-pentadienyltributyltin(1) with isoquinoline derivatives activated by acryloyl chloride afford the tetracyclic (+/-)-allo-berban systems stereoselectively.Similarly, the reaction of 1 with 3,4-dihydro-beta-carboline (11) gives the pentacyclic (+/-)-allo-yohimban system.The reaction is not affected by the stereochemistry of the 2,4-pentadienyltin reagent.A new substituted 2,4-pentadienyltin reagent, 3-(hydroxymethyl)-2,4-pentadienyltrimethyltin (19), is prepared via 3-(hydroxymethyl)pentadienyl dianion.The three-component coupling reaction of 19 with 11 and acryloyl chloride affords the (+/-)-allo-16-(hydroxymethyl)yohimban system, from which (+/-)nitraraine is readily synthesized.In addition, 1,3-asymmetric induction leads to the high diastereoselectivity realized in bicycloannulation (up to 94percent de) when (S)-3-<(tert-butyldimethylsiloxy)methyl>-3,4-dihydroisoquinoline (27), which is readily derived from L-phenylalanine, is used in the three-component coupling reaction.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, name: 6,7-Dimethoxy-3,4-dihydroisoquinoline, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 3382-18-1, Name is 6,7-Dimethoxy-3,4-dihydroisoquinoline, molecular formula is C11H13NO2

An efficient metal-free catalytic system has been developed based on hexagonal boron carbon nitride (h-BCN) nanosheets for the dehydrogenation of N-heterocycles with visible light; hydrogen gas is released in the process, and thus no proton acceptor is needed. This acceptorless dehydrogenation of hydroquinolines, hydroisoquinolines, and indolines to the corresponding aromatic N-heterocycles occurred in excellent yield under visible-light irradiation at ambient temperature. With h-BCN as the photocatalyst and water as the solvent, this environmentally benign protocol shows broad substitution tolerance and high efficiency.

The direct aza-Friedel-Crafts reaction of indole with 3,4- dihydroisoquinolines, 4,6-dihydro-3H-benzo[c]azepine and 6,7-dihydrothieno[2,3- c]pyridine led to the formation of 3-substituted indole derivatives. The reaction was also successfully extended to the synthesis of 3-substituted indole-2-carboxylic acids as new indole gamma-amino acid derivatives. All the reactions were optimized and were accelerated under microwave conditions.

The first total synthesis of the dimeric berberine alkaloid ilicifoline (ilicifoline B) is reported. Its carbon skeleton is constructed from ferulic acid, veratrole, and methanol. The synthesis reported herein employs starting materials solely derived from wood. The natural product is thus constructed entirely from renewable resources. The same strategy is applied to a formal total synthesis of morphinan alkaloids. The use of wood-derived building blocks (xylochemicals) instead of the conventional petrochemicals represents a sustainable alternative to classical synthetic approaches.

The enantiomers of 1,2,3,4-tetrahydroisoquinoline- and 6,7-dimethoxy-1,2,3,4-tetrahydroisoquinoline-1-acetic acids were prepared via Burkholderia cepacia lipase (lipase PS-D)-catalyzed kinetic resolution of the corresponding ethyl and 2-methoxyethyl esters using enantioselective (E > 200) hydrolysis in DIPE. The (S)-acids were produced enzymatically, whereas the (R)-acids were obtained via the chemical hydrolysis of the unreacted (R)-esters. The solvent and its water content had major effects on both reactivity and enantioselectivity. The methoxyethyl moiety of the ester had a key role concerning the reactivity of the substrates.
