Course objectives
Main objective of the seminar is to discuss and analyze the topics of the lecture Stereochemistry of organic compounds on some ilustrative and practical examples following the syllabus of the lecture.
Learning outcomes
Student will be able to identify problems related to three-dimensional structure of organic compounds and use the knowledge obtained I the course fro solution of model exercises related to symmetry, chirality, identification, analysis and separation of isomers. He/she will be able to solve problems of stereoselective reaction and asymmetric synthesis.
