Cyclisation chemistry of 4H-1,2,6-thiadiazines (2000)3,5-Dichloro-4H-1,2,6-thiadiazin-4-one 1 condenses rapidly at room temperature with 1,2-diaminobenzene, 2-aminothiophenol and sodium 2-aminophenoxide to give, respectively, the purple thiadiazinoquinoxaline 4a, red ...
Macrocyclic cyclo[n]malonates - Synthetic aspects and observation of columnar arrangements by X-ray crystallography (2006)A variety of achiral and chiral macrocyclic oligomalonates were synthesised in a one-step procedure through condensation of malonyl dichloride with α,ω-diols. We have investigated the applicability of this method by varying ...
