| 2,3,4,5-TETRAMETHYL-2-CYCLOPENTENONE Siv Thiab Synthesis |
| Siv | 2,3,4,5-Tetramethyl-2-cyclopentenone tuaj yeem siv los ua cov organic synthesis intermediates thiab tshuaj intermediates, feem ntau yog siv rau hauv kev tshawb nrhiav thiab kev tsim kho cov txheej txheem thiab cov txheej txheem tsim tshuaj. |
| Siv | 2,3,4,5-Tetramethyl-2-cyclopentenone tau siv rau hauv kev sib txuas ntawm chiral pre-ligands, (R)-3,3?-bis(tetramethylcyclopentadienyl)-2 ,2?-bismethoxy-1,1?-bisnaphthalene thiab (R)-3-tetramethylcyclopentadienyl-2,2?-bismethoxy-1,1?-bisnaphthalene los ntawm reacting nrog (R ) -3,3?-dilithium-2,2?-bismethoxy-1,1?-bisnaphthalene. |
| Synthesis |  Hauv qab lub khob ntim dej nruab nrog lub tshuab stirrer, ib qho xaum funnel thiab lub reflux condenser tau thauj khoom 2000g (23.2 mol) ntawm qhov pib ketone nrog 75% w/ w ntawm butylacetate ua cov kuab tshuaj, 0.35 molar sib npaug ntawm anhydrous magnesium chloride thiab aforementioned titanium catalytic tov muaj 0.06 molar sib npaug ntawm trichloropropoxytitanium complex. Lub resulting suspension tau nplawm lub zog thiab tso cai rau cua sov rau 90 degree. Tom qab ntawd 2 molar sib npaug ntawm cov acetaldehyde tau ntxiv dropwise tshaj 3h ntawm 90 degree. Cov tshuaj tiv thaiv tau txuas ntxiv rau ib teev ntxiv thiab txias rau 40 degree. Cov tshuaj tiv thaiv sib xyaw yog hydrolysed nrog 10% aqueous acetic acid tov thiab neutralized nrog 20% aqueous potassium carbonate tov. Qhov tshwm sim ntawm cov organic theem tau ncaj qha fractionated rau hauv chav kuaj Sulzer packed kem, kom them tau lub npe compound, raws li ib tug sib tov ntawm isomers trans:cis=85:15, nyob rau hauv 27% tawm los thiab cov enone (II) (ie {{ 18}}methyl-4-hexen-3-ib qho) hauv 31% tawm los. sib tov ntawm isomers trans:cis=(Bp=70-80 degree ntawm P=8 mbar); 4-methyl-4-hexen-3-ib=(Bp=45-65 degree ntawm P=8 mbar). 1H-NMR (isomer trans): 1.15 (d 3H); 1.19 (d 3H); 1.68 (s 3H); 1.88 (m 1H); 1.98 (s 3H); 2.25 (m 1H). 13C-NMR (isomer trans): 8.5; 14,6; 15.1; 17,7; 46.2; 48.4; 134.5; 171,6; 21 1.0. |
