Learning to recognize functional group relationships helps us to uncover reactions that could be used to synthesize those structures the process of thinking backwards in order to achieve a compound synthesis is known as retrosynthetic analysis it's illustrated in this webcast with six examples from. Some practice problems for the carbonyls test 3 retrosynthesis practice: design synthesis for the following, from alcohols with no more than 5 carbons you may also use esters, or any inorganic agents (pph3, pbr3, pcc, h2cro4, etc) 1 2 3 4 5 no other alkene structural isomers allowed. Interactive problems to aid students of organic chemistry. Can come prepared with witty new material that will amuse the graders 6) don't leave a synthesis question blank it is a sad state of affairs when you leave a synthesis problem blank (or any problem, for that matter) at the very least, try to make some retrosynthetic cuts and identify key reactions i always did my synthesis.
Strategies in synthetic planning modern stylistic points in retrosynthetic analysis jen alleva macmillan group meeting january 8th 2014 thursday, january 9, 14. Alright guys these next few questions are cumulative retro synthesis based on the past few chapters of reactions so you do need to still know those and i have made them so that they do represent common types of synthesis, ok but i've also made them all little bit harder than what i've seen on most tests, ok that's a good.
