ORGANIC SYNTHESIS AND SPECTROSCOPY - 2021/2

Module Overview

This is a high level module in organic chemistry, moving from the predominantly functional group approach of Level 4 beyond the skeletal construction approach of Level 5, to deal with modern and more conceptually challenging reactions and strategies for dealing with multistep syntheses. These are the reactions that are commonly used in contemporary organic synthetic chemistry.

Module content

Indicative content includes:

• Revision of organic reactions: Revision of mechanisms

• Retrosynthetic Analysis: Terms, definitions and basic concepts; retrosynthetic analysis: aromatic compounds; retrosynthetic Analysis: alcohols and carbonyl compounds; retrosynthetic analysis: 1,2, 1,3, 1,4 and 1,5dicarbonyl compounds; -unsaturated and 1,3dihydroxy compounds; retrosynthetic analysis: carbocyclic and heterocyclic; compounds

• Modern reactions: Polar reactions in synthesis, radical reactions in synthesis, pericyclic reactions in synthesis, asymmetric synthesis – an introduction

• Catalytic reactions in organic chemistry: Concept of catalysis. Mechanistic implications: creating a catalytic cycle. Reactions using metal catalysis; palladium-catalysed cross-coupling reactions: Heck, Sonogashira, Stille and Suzuki reactions; Pauson-Khand reaction. Small organic molecules as catalysts: BaylisHillman reaction; olefin metathesis

•Multicomponent reactions: Solid-phase synthesis and combinatorial chemistry

• Spectroscopy: Workshop 1: Introductory revision problems using 1D NMR (1H, 13C), MS, IR, UV. Use of the coupling constant, Karplus equation, coupling in aromatic systems and long range coupling; Workshop 2: Use of COSY, HSQC, DEPT, HMBC and NOESY spectra in structure determination with worked examples; Workshops 3 & 4: Structural determination of compounds using natural products and synthetic compounds (terpenoids; oxygen heterocyclics (chalcones, flavonoids); alkaloids) as examples

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate:

• Examination and coursework: Assimilation of knowledge and its application to problems in modern organic chemistry [LOs 1-6]

• In-class test/assessed workshop on spectroscopy: Ability to assign structure based on spectra [LOs 4]

Thus, the summative assessment for this module consists of:

• Coursework: Problem solving on aspects of the course (15%, 18 h over 8 weeks) [LOs assessed 1-3, 5]

• In-class test/assessed workshop on spectroscopy: (15%, 2 h ICT) [LOs 4]

• Examination: 1.5 hours, closed book (70%) [LOs assessed 1-5]

Formative assessment

Formal formative assessment is mainly in the spectroscopy workshops. There is also formative assessment in example problems posted to SurreyLearn for students to attempt and receive written or verbal feedback; also students can opt for informal formative assessment (submission of specimen exams, past papers, etc.) which will be marked and annotated. Feedback: Feedback is provided optionally on the formative practice problems. Coursework is marked and returned with feedback in time for the revision period.

Module aims

• provide students with the appropriate advanced material in organic chemistry to allow them to describe and methodically rationalize a representative range of standard modern reactions/syntheses
• provide students with the skills to identify organic compounds by spectroscopy

Learning outcomes

Methods of Teaching / Learning

The learning and teaching strategy is designed to:

give the student a good high level knowledge base, but also but the analytical and problem-solving skills to solve unseen (but related), and to attempt some new concepts; all within the context of current practice in organic synthesis.

The learning and teaching methods include:

• Lectures 20, plus two revision lectures = 22 L

• Problem-solving coursework based on the lectures (18 h over 8 weeks)

• Spectroscopy workshop (Contact = 4 x 2 h over 8 weeks, plus self-study time ca. 18 h, plus In-class test assessed workshop 2 h)

• General student independent study.

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
