Agarofuranoids with oxygen functions at C-1 and C-2 were synthesized by allylic oxidation.Ketone 2 gave compound 8 and 9 by Grignard reaction.The configuration
In this paper, the formation mechanism of the passive SEI film at the natural graphite anodes was investigated with the electrochemical impedance spectroscopy (
N-Acetyl-p, m or o-nitro-phenylethylamines and (HCHO)n were treated in 60% H2SO4/HOAc, via α-amidoalkylation to give 2-acetyl-mono(5, 6, 7 or 8)-nitro-1,2,3,4-
A novel reduction system is reported here in which the compounds with terminal C-C triple bond and disubstituted C-C triple bond react with NaBH4/Pd(PPh3)4 in a
Four 1,4-benzodioxane neolignans were first synthesized from pyrogallol, in which the Claisen rearrangement was used to afford three important C6-C3 units.
The spiro-calix[4]arenes 3a-b can be synthesized conveniently by the reaction of p-tert-butylcalix[4]arene (1a) or calix[4]arene (1b) with pentaerythritol tetra
