Term
|
Definition
- a compound containing the funcitonal group -SO3CH3
- prepared using methylsulfonyl chloride and an alcohol in the presence of a base
- phenomenal leaving group; makes alcohol into great leaving group after reaction
- can also serve as protecting group

Term
How are alcohols used as protecting groups? |
|
Definition
- aldehydes and ketones can be reacted with two equivalents of an alcohol or a diol forming acetals (primary carbons with two -OR groups and a hydrogen atom) or ketals (secondary carbons with two -OR groups)
- acetal or ketal can be reverted back to a carbonyl with an aqueous acid step
