Abstract
The structures of five naturally-occurring herbicidal nucleosides have been determined by spectral analysis. Three (5'-deoxyguanosine, coaristeromycin and S'-deoxytoyocamycin) are novel natural products while the remaining two (coformycin and adenine 9-β-D-arabinofuranoside) are known natural products which have not previously been reported to be herbicidal.
