A new access to 14-membered macrocycle: synthesis of model F-O-G ring of teicoplanin

A new strategy based upon the intramol. SNAr reaction was developed for the synthesis of I, the 14-membered F-O-G macrocyclic ring system of teicoplanin. Thus, treatment of acyclic precursor II (X = F) with CsF or K2CO3/18-crown-6 in DMF at room temp. for ...

A SNAr based facile synthesis of triaryl diethers, degradation products of vancomycin and related glycopeptide antibiotics

Jieping Zhu

A mild and efficient procedure has been developed for the synthesis of triaryl diethers and has been applied to the synthesis of diethers I (X1 = X2 = H; X1 = X2 = Cl; X1 = H, X2 = Cl), degrdn. products from glycopeptide antibiotics of the vancomycin famil ...

Photochemical etching of Cu and GaAs with Cl2 in the VUV

Majed Chergui, Bo Li

Photochem. reactions and etching efficiencies of polycryst. Cu and GaAs(100) with Cl2 were studied in the spectral range of 105-300 nm by using synchrotron radiation and for Cl2 pressures between 10-6 and 10 mbar. Dissocn. of Cl2 leads in the case of Cu to ...
