NEW PYRIDYLPYRROLE COMPOUND, ITS PRODUCTION AND AGRICULTURAL AND HORTICULTURAL GERMICIDE

摘要

PROBLEM TO BE SOLVED: To produce a new pyridylpyrrole compound useful as a safely usable agricultural and horticultural germicide, etc., having sure effects by reacting a specific phenylglycine with an acid anhydride and an ethynylpyridine in the presence of a trivalent phosphorus compound and a dehydrating agent. ;SOLUTION: This new pyridylpyrrole compound (salt) is represented by formula I [R¹ is H, a 1-10C alkyl, a 3-7C cycloalkyl, a 1-4C haloalkyl, etc.; R² is H, a 1-6C alkoxymethyl, etc.; X is H, a halogen, a 1-6C (halo)alkyl, a (substituted)phenoxy, etc.; Y is H, a 1-6C (halo)alkyl or a halogen; Z is H, a halogen, a 1-6C alkyl or nitro; (m) is 0-5; (n) is 0-4] and is useful as a safely usable agricultural and horticultural germicide, etc., having sure effects. The compound is obtained by reacting a phenylglycine represented by formula II with an acid anhydride and an ethynylpyridine represented by formula III (Z' is H or a 1-6C alkyl) in the presence of a trivalent phosphorus compound and a dehydrating agent.;COPYRIGHT: (C)1997,JPO
