IntroductionOrganic Chemistry research involves the synthesis of organic molecules and the study of their reaction paths, interactions, and applications. Advanced interests include diverse topics such as the development of new synthetic methods for the assembly of complex organic molecules and polymeric materials, organometallic catalysis, organocatalysis, the synthesis of natural and non-natural products with unique biological and physical properties, structure and mechanistic analysis, natural product biosynthesis, theoretical chemistry and molecular modeling, diversity-oriented synthesis, and carbohydrate synthesis.

Synthesis studies

Organic compounds that has been never synthesis before

Strategy:

Pharmaceutical chemistry research studies

on the design and synthesis of novel drug candidate molecules is a good representative example to this category

Organic compounds that has been synthesis previously

:Strategy

In these synthesis types is the discover of a novel synthetic approach that supplies high yields and the lowers the synthesis cost

Work-up and purification studies

Work-up

Purification

Which factors are important in work-up

Reaction condition

Reaction yield

Chemical and physical properties(reactants, regents, products)

Number of products and reactants

Yield calculation

Mechanism of acetophenone

Literature search

Why literature is very important?

Notice:An effective literature search must be performed before making a practice in laboratory
