What is planning a multi-step synthesis?Show answer
Multi-step synthesis joins individual functional-group conversions into a route. Useful conversions to combine include: - alkene to alcohol (steam, catalyst) or to haloalkane (HX); - haloalkane to alcohol (warm aqueous ), to nitrile (ethanolic , adding a carbon), or to amine (excess ammonia); - nitrile to amine () or to carboxylic acid (acid hydrolysis); - primary alcohol to aldehyde (distil with acidified dichromate) then to acid (reflux); - acid to ester (alcohol, conc ) or to acyl chloride ().
