Full Reaction Searching
Introduction

This topic describes how to locate organic synthetic methods using Explore Reactions.

When to use

Use full reaction searching when you want to locate organic synthetic pathways with specific structural transformations.  Structures can be specified on:

  • Both sides of the reaction arrow
  • The reactant side of the reaction arrow only
  • The product side of the reaction arrow only
Behind the scenes

Full reaction searching accesses records that focus on synthetically useful procedures.  For example:

  • New, more convenient, or improved synthetic methods
  • Procedures for improving yields
  • Applications of new reagents
Preview

Locating full reactions containing a structural transformation of interest is a two-step process:

  1. Locate relevant reactions for the transformation of interest
  2. (Optional) Refine results using precision criteria
Example

Locate reactions matching the following structural transformation:

3

Draw the reaction transformation of interest.

Tip: Apply the following tools to control answer precision:

  • Lock Rings tool to control ring formation
  • Reaction Arrow tool to define the reaction participants
  • Atom Mapping tool to map an atom between reactant and product
