· luoroÂ·acetic acid are used in peptide synthesis to remove examples of these entities known as BÂ·OÂ·C and FÂ·MÂ·OÂ·C. Ethylene glycol can be used as one of these reagents by converting a carbonyl group into an acetal, thus preventing reduction of the carbonyl by a hydride or Grignard reagent.
A textbook titled for these entities was written by Philip J. Kocienski. Ian Young and Phil Baran suggested bio-mimetic methods as a way of avoiding the decrease in yield caused by having to use these entities. Norrish type II reactions can be used to append nitroÂ·benzyl examples of these entities which have the advantage of being photolabile ("photo"-lay-"bile"). In the  rst step of a Favorskii reaction, a propÂ·arÂ·gyl alcohol is generated to serve as one of these entities. PiÂ·perÂ·iÂ·dine and triÂ· luoroÂ·acetic acid are used in peptide synthesis to remove examples of these entities known as BÂ·OÂ·C and FÂ·MÂ·OÂ·C. Ethylene glycol can be used as one of these reagents by converting a carbonyl group into an acetal, thus preventing reduction of the carbonyl by a hydride or Grignard reagent. For 10 points, name these chemical reagents which are reversibly added to a particular functional group to prevent it from reacting in a multi-step organic synthesis.
