The present invention relates to novel substituted pyridines/pyrimidines of the formula I
where A is CH or N; X is NH, oxygen or S(O)q where q is 0, 1 or 2; Y is a direct bond or CH2; Z is oxygen, NR7 or S(O)m is 0, 1 or 2, and the radicals R1, R2, R3, R4, R5, R6 and R7 are as defined in the description, to processes for their preparation, and to their use as pesticides, fungicides, ovicides or as veterinary medicaments.
Novel sulphur containing food flavor substances are provided containing an oxygen or sulphur atom in a five or six membered ring structure, one alkyl or hydroxy alkyl substituent at at least either of the carbon atoms adjacent to the hetero atom and having at least one sulphur or oxygen atom attached to another carbon atom of the ring structure.

Methyl-3-thiacyclopentanarnines 4a-c were reacted to their sulfamic acid sodiurn salts 5a-c, and their structures determined.Only sodium 4-methyl-3-thiacyclopentylsulfamate (5b) is sweet. The oxa analogues 8a-b however are tasteless.
