  A Three-Component Photoreversible Tag for Thiols

  摘要：

  A one-pot coupling of a 1,3-diketone, an aldehyde, and an alkanethiol has been developed to produce a protected sulfide. Through use of an o-nitrophenylbenzaldehyde, this method provides a one-step route to a photochemically reversible thiol-protecting group. The kinetics of photolysis were established using H-1 NMR analysis, which allows for the rate to be based on the entire reaction scheme.
