SYNTHESIS STRATEGIES MODERN IN ORGANIC CHEMISTRY
LEARNING OUTCOMES OF THE COURSE UNIT
The main objective of the course is to give to the students the tools for an efficient design for the synthesis of complex organic compounds on the light of the request of the modern eco-compatible chemistry
It is requested the have attended the Organic Chemistry I and Organic Chemistry II courses and the related Laboratory courses

ASSESSMENT METHODS AND CRITERIA
The course is organized in two parts: a theoretical part concerning the synthetic strategies and a second part with exercises concerning the synthesis of complex organic compounds.
