Compounds of Formula (I) are disclosed which are useful as fungicides, wherein Q is: (Q−1) or (Q−2), Z is (Z−1); (Z−2); (Z−3) or (Z−4); X is —O—, —CH(R11)— or ═C(R11)—; R1 is H or C1-C2 alkyl; R2 is H; C1-C6 alkyl; C3-C6 cycloalkyl; or phenyl optionally substituted with halogen, cyano, C1-C2 alkyl or C1-C2 alkoxy; and R3-R11 are as defined in the disclosure. Also disclosed are compositions containing the compounds of Formula (I) and a method for controlling plant diseases caused by fungal plant pathogens which involves applying an effective amount of a compound of Formula (I).

An efficient three-step methodology developed for the preparation of 1,2-amino alcohols. In the first step a rapid coupling between bromoketones and potassium phthalimide in ionic liquid produced alpha-phthalimido ketones in quantitative yields, which is followed by a facile reduction using NaCNBH3 in acetic acid to give corresponding phthalimido alcohols and finally effecting hydrazinolysis in water at 60 degrees C to yield biologically important 1,2-amino alcohols.
