Octa(peripheral-amide)substituted zinc(II) phthalocyanine 6 was obtained from 5 and zinc acetate in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene. Phthalocya-nine 7 was prepared via reduction of 6 with diborane. Treatment of 7 with methyl iodide afforded cationic dye 8....
[translate] aThus, reduction of amide 13 with LiAlH4 followed by acidic work-up led to the hydrochloride of amine 14 in 90% yield. 因此,氨化物13的减少与酸性跟随的LiAlH4在90%出产量工作导致氯化物胺物14。 [translate] 英语翻译 日语翻译 韩语翻译 德语翻译 法语翻译 俄语翻译 阿拉伯语翻译 西班牙...
The main mechanistic proposal for both pathways consists of a first addition of hydrogen to the amide, or its tautomer iminol, to afford the corresponding hemiaminal intermediate22that can undergo hydrogenolysis giving the alcohol plus the lower amine, in the case of the C–N pathway (Fig.1a)...
Borane-amine complexes provide an unusually fast and selective reduction of a deoxynucleoside N-acyl group to a corresponding N-alkyl group. Three different nucleosides (dG, dA, and dC) each having one of three N-protecting groups (benzoyl, isobutyryl, or acetyl) were used to prepare N-alkyla...
aCareful attention to stoichiometry was required to avoid over reduction of amide 93, which was critical to achieve high-yielding (76%) salt formation of fingolimod HCl (VI) through the use of 6 N ethanolic hydrochloric acid. 要求对化学计量学的仔细的关注避免氨化物93的结束减少,是重要通过对 (...

Staudinger-Bertozzi ligation. A nucleophilic phosphine attacks the organic azide, the product of which rearranges to form a four-membered transition state. Upon the release of N2, the nitrogen attacks carbonyl group to form a five-membraned ring intermediate whose hydrolysis yields a stable amide ...
U.S. Pat. No. 3,749,751 discloses the use of an amide or pyrrolidone-type compound for reduction of formaldehyde in coating solutions containing methylated carbamates. U.S. Pat. No. 3,723,377 discloses the use of 4,5-dihydroxy-2-imidazolinone (DHEU) and its derivatives to reduce form...
In the present invention there is disclosed a process for synthesizing N-(2-(R)-hydroxy-1-(S)-indanyl)-2(R)-phenylmethyl-4(S)-hydroxy-5-(1-(4-(3-pyridylmethyl)-2(S)-N'-(tert-butylcarboxamido)piperazinyl)pentane amide of the general formula J or a hydrate thereof, which process ...
