Chemical Research Letters, May 2021. The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. 20880-92-6, Name is ((3aS,5aR,8aR,8bS)-2,2,7,7-Tetramethyltetrahydro-3aH-bis([1,3]dioxolo)[4,5-b:4′,5′-d]pyran-3a-yl)methanol, SMILES is OC[C@@]1([C@H]([C@@H]([C@@H](CO1)O2)OC2(C)C)O3)OC3(C)C, in an article , author is Gomaa, MAM, once mentioned of 20880-92-6, Quality Control of ((3aS,5aR,8aR,8bS)-2,2,7,7-Tetramethyltetrahydro-3aH-bis([1,3]dioxolo)[4,5-b:4′,5′-d]pyran-3a-yl)methanol.
Reaction of diimines and azines with diphenylcyclopropenone
1-Cyclohexyl-2-cyclohexylaminomethylene-4,5-diphenyl-1,2-dihydropyrrol-3-one 4a and 1-aryl-2-arylamino-methylene-4,5-diphenyl-1,2-dihydropyrrol-3-ones 4b, c as the E-form are synthesized by the reaction between N,N’-dicyclohexylethane-1,2-diylidenediamine 2a and N,N’-diarylethane-1,2-diylidenediamines 2b, c with diphenylcyclopropenone 1 through a formal [2 + 3] cycloaddition reaction. The structure assignment of 4a is confirmed on the basis of an X-ray crystal-structure determination. Similarly, diaryl azines 8a-c react with 1 through a formal [2 + 3] cycloaddition reaction to give the non-isolable product Delta(4)-pyrrolin-3-ones 10a-c which undergo oxidative rearrangement to afford ultimately the indenone derivatives 9a-c.
The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules.
