Investigation of the hydroxyl directing effect on the Paternò–Büchi reaction on 5-(2-triisopropylsilyloxazolyl)methanol derivatives

D'Auria, Maurizio,Racioppi, Rocco,Rofrano, Federico,Stoia, Sonia,Viggiani, Licia

, p. 5142 - 5148 (2016)

The photochemical coupling of 5-oxazoylmethanol derivatives with benzophenone and benzaldehyde showed that the hydroxyl directing effect in the Paternò–Büchi reaction described in the case of allylic alcohols and furylmethanol derivatives can also be pres

A convenient oxazole C-2 protecting group: The synthesis of 4- and 5-substituted oxazoles via metalation of 2-triisopropylsilyloxazoles

Miller, Ross A.,Smith, Randi M.,Marcune, Benjamin

, p. 9074 - 9076 (2007/10/03)

Metalation of oxazoles at the 4 and 5 position was achieved after regioselective C-2 silyl protection. Removal of the protecting group was then accomplished under mild conditions allowing for a straightforward preparation of C-5 monosubstituted and C-4,5
