DOCUMENT TYPE: Journal CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) Cyclic amidines I (R = Ph, CCl3, n = 3,4) were obtained by treatment of RCONCO with the corresponding N-methylpyrrolidinone or piperidone. RCONCO treated with an N-acylpiperidine or morpholine gave 40-100% II (R = CCl3, CF3, R1 = H, Me, X = CH2, O). .

PRIORITY: GB 2003-15787 4 Jul 2003. DOCUMENT TYPE: Patent CA Section: 33 (Carbohydrates) Section cross-reference(s): 5 The present invention relates to novel 2,7-dioxo-bicyclo[4.3.0]non-5-yl-urea derivs. of formula (I) [wherein R = H, C1-6 alkyl (e.g.Several reagents with their cas registry numbers 828914-79-0 and 3019-71-4 are used here. Me); the RO group is cis- or trans- to the NH2CONH group; R1 = H, formyl, C1-8 alkylcarbonyl, C3-8 cycloalkylcarbonyl, optionally substituted benzoyl; X = a N-linked heterocyclic group of the formula Q, Q1, or Q2; wherein R2 = H, C1-4 alkyl (esp. Me), halo], to processes for their prepn., and to certain intermediate chems. used in those processes. It also relates to the use of the compds. as biocides, to compns. contg. biocidally effective amts. of the compds. and to methods of combating pathogens using the compds. These nucleoside derivs. possess useful plant protecting properties and may advantageously be employed in agricultural practice for controlling or preventing the infestation of plants by phytopathogenic microorganisms, esp. fungi. Thus, compd. (II) (multistep prepn. from D-ribose given) was stirred with bis(trimethylsilyl)-N-acetylcytosine and N-iodosuccinimide in the presence of triflic acid in CH2Cl2 at room temp. for 5 h to give uridine deriv. (III) (R1 = pivaloyl, R3 = N3, R4 = Ac) which was treated with Me3P in THF for 30 min at room temp. and then with H2O and refluxed for 40 min to give III (R1 = pivaloyl, R3 = NH2, R4 = Ac). The latter compd. underwent addn. reaction with trichloroacetyl isocyanate in CH2Cl2 at room temp. for 60 min to give the urea III (R1 = pivaloyl, R3 = Cl3CCONHCONH, R4 = Ac) which was stirred with a mixt. of MeOH and 40% aq. methylamine at room temp. for ~3 days to give III (R1 = R4 = H, R3 = H2NCONH). III (R1 = R4 = H, R3 = H2NCONH) was tested against a variety of foliar fungal diseases of plants and at 100 ppm controlled 100% Stagonospora nodorum, 100% Blumeria graminis f. sp. tritici, and 83% Puccinia triticina. .
