Natural product retrosynthesis
So retrosynthesis: note: fgi’s can be carried out on intermediates/products note especially: helps in the synthesis of 1,3 diols enolate anions as ambident nucleophiles eg 2 reaction of active methylene compounds with carbonyl compounds (knoevenagel condensation) usually uses weak base/weak acid as catalyst, (r 2. Chemists have traditionally drawn inspiration from nature and sought to imitate natural chemical processes and materials through biomimetic synthesis, asymmetric catalysis and natural product (analog) synthesis 1 beginning in the mid-1960s, retrosynthetic analysis began to revolutionize the way synthetic chemists designed routes to target. On friday the 27 th of february, burlington house was the venue for the final of the 2 nd national retrosynthesis competition this event was jointly organised by the heterocyclic and synthesis group of the royal society of chemistry, and the fine chemicals group and young chemists panel of the sci, under the lead of rob.
