Mortality: No deaths occurred following a 4-h exposure to 2000 ppm TMA; 3 of 6 rats exposed to 3500 ppm died during the exposure period Clinical signs: other: During exposure, all rats showed labored breathing, nasal and oral discharges, and neither moved nor responded to sound. Rats exposed to 3500 ppm also had dry red nasal and ocular discharge during the early stages of the postexposure period. Radical Arylation Reactions of 4, 6, 8‐Trimethylazulene.

2004-04-02 Flavin-containing monooxygenase 3 (FMO3) is known primarily as an enzyme involved in the metabolism of therapeutic drugs. On a daily basis, however, we are exposed to one of the most abundant substrates of the enzyme trimethylamine (TMA), which is released from various dietary components by the action of gut bacteria. FMO3 converts the odorous TMA to nonodorous TMA N -oxide (TMAO), which is 2012-12-18 catalysts, the g eneration of phthalides is restricted when bulk y azulen es, as 4,6,8-trimethylazulene, was reacted due to the high steric hindrance induced by the nei ghbo rhood of the two Experimental procedure 4): To a solution of veratrole (30 mL, 234 mmol) and N,N,N',N'-tetramethylethylenediamine (35.4 mL, 234 mmol) in ether (240 mL) is added dropwise over 15 min n-butyllithium (2.47 mol/L hexane solution, 94.8 mL, 234 mmol) at 0 °C under an N 2 atmosphere. The resulting suspension is stirred at 22 °C for 18.5 h and then recooled to 0 °C. Trimethylamine complexes of alkylboranes, prepared by reduction of the corresponding alkyl-boroxines in the presence of trimethylamine < 59JA5836 >, have been found to undergo reaction with alkanethiols at 60–100 °C to yield the corresponding dialkyl alkylthioboronates in yields of up to 72% < 60JA748 >. The use of trimethylamine borane for reaction with high boiling thiols has also been Dipeptide synthesis from N-[3-(2-furyl)acryloyl]-acylated (Fua-) amino acid ethyl ester and amino acid amide catalyzed by wheat bran carboxypeptidase (carboxypeptidase W) was studied. The optimum pH for peptide formation was at pH 8; more than 60% of the initial N -Fua-L-phenylalanine ethyl ester was converted to N -Fua-L-phenylalanylglycinamide under optimum conditions.
