Annotation -
The course Stereoselective Organic Syntheses includes basic organic stereochemistry, analytical methods applicable to the studies of stereoizomers and stereoselective reactions, and methods of stereoselective syntheses of organic compounds. A series of diastereoselective and enantioselective organic reactions will be presented, and advantages or disadvantages of particular synthetic approaches will be discussed.

Course completion requirements -

The subject is evaluated by 2 semestral tests and a final exam.

During the semester there are two tests (usually at 6. and 13. week). To pass it is necessary to gat at least 50 points of each test from possible 100.

The final exam is possible after passing the semestral tests. The exam is written. It is evaluated as follows: 0-50p F, 50-64p E, 65-74p D, 75-79p C, 80-89p B, 90-100p A. Oral part is possible when the student wants a better mark and used already all 3 possible attempts on the written exam.

Requirements to the exam - Czech

Předmět je zakončen zápočtem a zkouškou.

Zápočet je udělen na základě semestrálních testů. Během semestru se píší dva testy (obvykle v 6. a 13. týdnu). K získání zápočtu musí student v každém z testů získat nejméně 50 bodů ze 100 možných.

Ke zkoušce může student přistoupit po získání zápočtu. Zkouška se skládá z písemně. Je hodnocena následovně: 0-50b F, 50-64b E, 65-74b D, 75-79b C, 80-89 B, 90b-100 A. Ústní část může student absolvovat pokud není spokojen se známkou z písemné zkoušky a již vyčerpal termíny písemných zkoušek.
