A practical amine-free synthesis of symmetric ureas and thioureas by self-condensation if iso(thio)cyanates
(Thieme Stuttgart, 1999)
Isocianates and isothiocyanates are readily transformed into the corresponding symmetric N,N'-disubstituted ureas and thioureas upon treatment with pyridine-water with no formation of side products. Evidence is shown for ...
Synthesis of 3-aminolactams as X-Gly constrained pseudodipeptides and conformational study of a Trp-Gly surrogate
(AMER CHEMICAL SOC, 2003-12-12)
3-Amino-delta-valerolactams trans-11a-c were synthesized through conjugate addition and Curtius rearrangement and converted into Fmoc-{Trp-Gly}, Fmoc-{Ile-Gly}, and Fmoc-{Phe-Gly} pseudo-dipeptides. Conformational analyses ...
