Abstract: Graphene oxide (GO), an inexpensive, environment-friendly, and metal-free carbocatalyst, used for the N-formylation of amines is developed. In this reaction, GO shows good activity, selectivity, and recyclability. This strategy has an array of advantages, such as being metal free, without additive, wide-scope protocol, scalable with a low catalyst loading of 3 wt%, use of readily available and recyclable carbocatalyst, and DMF as a readily available formyl source. Furthermore, this strategy provides an avenue for the convenient hydroformylation of various amines. Graphical abstract: [Figure not available: see fulltext.].

Azomethine ylides are accessed under mild conditions via benzoic acid catalyzed condensations of 1,2,3,4-tetrahydroisoquinolines or tryptolines with aldehydes bearing a pendent dipolarophile. These intermediates undergo intramolecular [3 + 2]-cycloadditions in a highly diastereoselective fashion to form polycyclic amines with four new stereogenic centers. Challenging substrates such as piperidine, morpholine, and thiomorpholine undergo the corresponding reactions at elevated temperatures.

Cyclic amines and 1,3-diketones readily react under microwave irradiation to form ring-fused pyrroles in a single operation. A competing retro-Claisen pathway is efficiently suppressed by employing p-toluenesulfonic acid as an additive.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Safety of 6,7-Dimethoxy-1,2,3,4-tetrahydroisoquinoline, you can also check out more blogs about1745-07-9

Graphene oxide (GO) has been developed as an inexpensive, environmental friendly, metal-free carbocatalyst for the dehydrogenation of nitrogen heterocycles. Valuable compounds, such as quinoline, 3,4-dihydroisoquinoline, quinazoline, and indole derivatives, have been successfully used as substrates. The investigation of various oxygen-containing molecules with different conjugated systems indicated that both the oxygen-containing groups and large pi-conjugated system in GO sheets are essential for this reaction.

(equation presented) Soluble polymer bound reagent 1 has been prepared to cleave tertiary amines from REM resin. Normally, amines cleaved from REM resin require extraction or chromatography to remove excess cleavage reagent and its byproducts. The solubility profile of non-crosslinked polystyrene (NCPS) based reagent 1 eliminates the need for such purification and allows for the direct isolation of a library of pure tertiary amines through simple filtration and concentration operations.
