Summary:Provided herein are processes for the preparation of stereomerically enriched compounds of Formulas I-014, I-020, I-064, I-074, I-082, I-089, I-090, I-095, I-171, I-181, I-184, I-186, I-189, I-191, I-192, I-193, I-205, I-206, I-208, I-211, I-212, I-213, I-220, I-229, I-231, I-233, I-234, I-246, I-251, I-258, I-259, I-262, I-263, I-285, I-323 and I-400. The compounds described herein exhibit activity as pesticides and are useful, for example, in methods for the control of fungal pathogens and diseases caused by fungal pathogens in plants. A preferred process is directed to preparing a stereomerically enriched compound of Formula V-1 or V-2-F by assymetrical reduction in the presence of a chiral organometallic catalyst. L'invention concerne des procédés de préparation de composés stéréoisomériquement enrichis des formules I-014, I-020, I-064, I-074, I-082, I-089, I-090, I-095, I-171, I-181, I-184, I-186, I-189, I-191, I-192, I-193, I-205, I-206, I-208, I-211, I-212, I-213, I-220, I-229, I-231, I-233, I-234, I-246, I-251, I-258, I-259, I-262, I-263, I-285, I-323 et I-400. Les composés de l'invention présentent une activité en tant que pesticides et sont utiles, par exemple, dans des procédés de lutte contre des pathogènes fongiques et des maladies provoquées par des pathogènes fongiques dans les plantes. Un procédé préféré de l'invention concerne la préparation d'un composé stéréoisomériquement enrichi de formule V-1 ou V-2-F par réduction asymétrique en présence d'un catalyseur organométallique chiral.
