N-Trityl-2-(tritylsulfanyl)aniline
The title compound, C(44)H(35)NS, is a derivative of amino-thio-phenol and possesses a protected S-triphenyl-methyl thio-ether and an N-triphenyl-methyl-amine functional group. The trityl groups show an anti orientation, with C-C-N-C and C-C-S-C torsion angles of -151.0 (3) and -105.3 (2)°, respectively. There is an intra-molecular N-H⋯S hydrogen bond.
متن کاملSynthesis of N-Trityl-L-homoserine
L-Homoserine was tritylated via its silylated product with Me2SiCl2 or Ph2SiCl2 in 65-68% yield. Also N-Trt-L-methionine upon treatment with Mel and degradation of the resulting sulfonium salt with KOH yielded N-Trt-L-homoserine in 75% yield. Both routes provided N-Trityl-L-homoserine with identical physical data. In contrast to N-alkyloxycarbonyl-L-homoserine derivatives, N-Trt-L-homoserine sh...
متن کاملSynthesis and Crystal Structure of Benzyl (-)-(2 S)-l-trityl-2-aziridinecarboxylate
Derivatives of aziridinecarboxylates play an im portant role in bioorganic chemistry, e.g. for the syn thesis of amino acids [1-3], antibiotics [4, 5] and selective inhibitors [6]. Recently, we reported that 2-aziridinecarboxylic acid may represent a promis ing handle to develop aziridine-containing com pounds as a new class of cysteine proteinase inhibi tors [7], In this context 1 could c...
متن کاملGreen and efficient synthesis of functionalized 3-amino-2-oxofuranes using trityl chloride
Extremely facile and efficient procedure has been developed for the synthesis of alkyl 2,5-dihydro-2-oxo-5-aryl-3-(arylamino) furan-4-carboxylate in the presence of trityl chloride (TrCl) as an organic catalyst in ethanol at ambient temperature. One-pot three-component reaction of aromatic amines, dimethyl and/or diethyl acetylenedicarboxylates and aryl aldehydes offorded the corossponding 3-am...

^ d jw0j (w0) + ^ d jw1j (w1) 2 + E(jwj + 1) = d 0 (w0) + d 0 (w1) 2 so d 0 obeys the average law (without conservation). Proof.[of Theorem 19] Note the d 0 constructed in Theorem 18 is generally not conservative. We will parallel Theorem 4, by constructing a slothful two-sided quasipolynomially precise cover. The construction of a conservative cover from a slothful cover preserves two-sided qu...
