(needles) has m 19-19.5o, b 92o/15mm, the amide has m 133o (yellow needles from H2O), the O-acetyl derivative has m 135o (rapid heating and the liquid resolidifies at 118o), and the O-benzoyl derivative has m 132o (aqueous EtOH). [IR: Hales et al. J Chem Soc 3145 1954...
, textile dyeing auxiliaries, metal surface treatment agent and acid chloride, anhydride, amide, polyester, organometallic salt, water salicylaldehyde, chlorocarboxylic acid and the raw materials of other organic synthesis. In addition, in medicine, it can also be used as etherifying agents and ...
acid chlorides4r–4vwere obtained as the sole products in high yields. These results indicated that the insertion of [PdH] species into the double bond of the alkenes is irreversible in our hydrochlorocarbonylation. Notably, acenaphthylene and androstenone were tolerated in the reaction to afford ...
Reduction of the amide functionality in the methylated derivative with a LiBH4/LiBHEt3 mixture followed by acidic hydrolysis and subsequent ion-exchange chromatography produced the corresponding (S)-α,β-diaminophosphonic acid in 44% yield (Scheme 60).106b It is important at this point to ...
and the imidazolyl ring of histidines. However, acylation of cysteine, tyrosine, andhistidineside chains forms unstable complexes that are easily reversible to regenerate the original group. Only amine functional groups of proteins are stable to acylation with anhydride reagents, formingamidebonds (Fraen...
and to succinic acid by hydrogenation (ethanol / palladium on carbon). It reacts with thionyl chloride or phosphorus pentachloride to give the maleic acid chloride (it is not possible to isolate the mono acid chloride). Maleic acid, being electrophilic, participates as a dienophile in many Diel...
