Overall aims and purpose

This module comprises different aspects of organic chemistry, and build on the organic functional group chemistry and stereochemistry discussed in modules FXX1101 and FXX1103.

The first part of the lecture course will focus on anion chemistry. Thus, their formation and chemical properties will be discussed, and a number of synthetically important reactions will be presented. Further retrosynthetic analysis - a problem-solving technique for target-orientated synthesis - will be introduced and the knowledge on stereochemistry expanded. This is achieved through a mixture of formal lectures (online or pre-recorded), guided self-study material and in class problem-solving (online). The module will be assessed through a formal exam and also through online assignments.

Course content

The first part of the module (6 units, PJM) will cover the following aspects; carbanion formation and stability, resonance and delocalisation, the nature of electrophiles in organic reactions, α-alkylation (including Knoevenagel type reactions), and activating groups. Within this context, the Aldol reaction, Aldol condensation, Claisen reaction, and its variations, crossed Aldol reactions and crossed Claisen reactions, the Michael addition, Robinson annelation, the Wittig reactions (including variations), and the decarboxylation reaction will be discussed. All reactions will be put into the context of their synthetic applications and their reaction mechanisms. The second part of this module (22 units, ML) will introduce the concept of retrosynthesis and continue on expanding the knowledge of stereochemistry and synthesis (reactions and mechanisms). The following aspects will be covered: Retrosynthetic analysis - terminology (e.g., retrosynthesis arrow, synthons, various disconnections, FGI, SM, TM, SE) and its application for a variety of organic molecules, advanced functional groups (e.g., hydrazones, oximes), synthetic strategies (protecting group chemistry, selectivity, specificity), introduction and expansion on reactions and their mechanism (including selectivity and stereochemistry), reagent chemistry (e.g. for oxidations, reductions, substitutions, additions), resolution of optical isomers, and chirality without stereogenic centres. New - or earlier only briefly mentioned - reactions(e.g., Diels Alder reaction, Hydroboration, Metathesis) will be introduced, and they will be - as those discussed during the first part of the module - explored in a range of retrosynthetic problems. The material will be taught through a mixture of online classes/tutorials, self-study material provided on Blackboard (e.g., prerecorded material, bookwidgets, socrative etc), as well as by directed reading (textbook and Blackboard).

Assessment Criteria


Knowledge and understanding of the content covered in the course is basic; Problems of a routine nature are generally adequately solved; Transferable skills are at a basic level.


The knowledge base covers all essential aspects of subject matter dealt with in the programme and shows good evidence of enquiry beyond this. Conceptual understanding is good. Problems of a familiar and unfamiliar nature are solved in a logical manner; solutions are generally correct and acceptable. Performance in transferable skills is sound and shows no significant deficiencies.


The knowledge base is extensive and extends well beyond the work covered in the programme. Conceptual understanding is outstanding. Problems of a familiar and unfamiliar nature are solved with efficiency and accuracy; problem-solving procedures are adjusted to the nature of the problem. Performance in transferable skills is generally very good.

Learning outcomes

  1. Students should be able to demonstrate fundamental knowledge on functional group interconversion and carbon-carbon bond formation, i.e. having developed a fundamental understanding of the underlying mechanistic rationales for reactivity (i.e. being able to draw curly arrow mechanism, perform a formal retro-synthesis on an oligo functional target molecule, recognition of important intermediates), selectivity (i.e. distinguishing and rationalising different types of selectivity) and reagents (i.e. knowledge of standard reagents and their use).

  2. Students should be able to demonstrate the use of Professional Chemistry Language on an Independent User Level (confident and correct use and understanding of basic concepts, mechanisms, terminology, and techniques within the course-level).

  3. Students should be able to show problem-solving and critical thinking skills by critically analysing, designing and evaluating non-complex synthetic problems within the course-level.

  4. Students should be able to verbalise and apply key concepts and stereochemistry specific terminology to a variety of chemical problems (e.g., assigning absolute configuration including in complex compounds containing multiple stereogenic centres, determining the stereochemical relationship between molecules containing multiple stereogenic centres, fundamental control of stereochemistry and resolution of stereoisomeric mixtures).

  5. Students should be able to demonstrate a fundamental knowledge of specifically anion chemistry, their properties and their chemistry (including the ability to draw curly arrow mechanisms to reactions discussed or similar to reactions discussed during the module).
