The main objective of the course is to give to the students the tools to efficiently design 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
Course unit content

Oral lesson. At the end of the course will be carried out group exercises.
Assessment methods and criteria
Oral examination consisting in the design of the synthesis of two target molecules
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.
