How are retrosynthetic analysis and synthetic planning related?
Retrosynthetic analysis is based on known reactions (e.g the Wittig reaction, oxidation, reduction etc). The synthetic plan generated from the retrosynthetic analysis will be the roadmap to guide the synthesis of the target molecule.
What is the Disconnection Approach to synthons and reagents?
Disconnection Approach Synthons and Reagents dn synthon: Functionalized nucleophile (d, donor) with the heteroatom of the functional group joined to the nthcarbon atom. an synthon: Functionalized electrophile (a, acceptor) with the heteroatom of the functional group joined to the nthcarbon atom.
How is a disconnection represented in retrosynthetic analysis?
Symbols of Retrosynthetic Analysis 13 A disconnection is represented by a wavy (⌇) line through the bond being disconnected,. A retrosynthetic arrow (⇒): This open arrow represents going from the target molecule “backwards” to simpler molecules (retrons).
Why is it called retro synthesis in chemistry?
It is an analytical technique used in which the deconstruction or fragmentation of targeted organic molecule is done to produce starting material, generally called as “synthon”. Fragments generated via a particular pattern of break down. It is called as retro synthesis because it is a reversible process of chemical synthesis.
