A novel microbial method for the production of 2',3'-dideoxynucleosides by transdideoxyribosylation has been developed. By screening microorganisms producing 2',3'-dideoxyadenosine (DDA) from 2',3'-dideoxyuridine (DDU) and adenine, Escherichia coli AJ 2595 was selected as the best producer. Optimal pH and temperature for the DDA-producing reaction were ca. 6.5 and 50 degrees C, respectively. Pi...

Tin carbodiimides have been reported with various compositions, prepared via solid-state metathesis reactions by heating tin halides and lithium carbodiimide at moderate temperatures. The formations of two new compounds, LiSn2Br3(CN2) Sn4Br2(CN2)3 are monitored differential thermal analysis (DTA), crystal structures as refined on basis X-ray diffraction studies. structure can be described inter...
