Photochemical Ring Contraction of Dihydro-1,4-benzothiazines
Costantini, Claudio,Testa, Gennaro,Crescenzi, Orlando,d'Ischia, Marco
, p. 3365 - 3366 (1994)
The pheomelanin precursors 1a and the related dihydro-1,4-benzothiazines 1b-f undergo ring contraction upon irradiation with pyrex-filtered UV light to give 2-methylbenzothiazoles 2a-f in good yields.

High-yielding cleavage of (aryloxy)acetates
Spurg, Anke,Waldvogel, Siegfried R.
, p. 337 - 342 (2008/09/18)
A reliable and high-yielding one-pot sequence for the removal of O-carboxymethyl moieties from phenols is presented. When diethylphosphoryl azide is employed as the azide transfer reagent in the Curtius rearrangement and glycerol in the subsequent hydrolytic workup, the protocol can be reliably applied to a very broad scope of substrates.
