Structures and reactivities of O-methylated Breslow intermediates

Maji, Biplab,Mayr, Herbert

supporting information, p. 10408 - 10412 (2012/11/07)

As close as you can get: Since Breslow intermediates usually exist in their keto form, their O-protected tautomers may be considered as their closest isolable relatives. A series of these compounds have been synthesized, their structures determined, and the kinetics of their reactions with electrophiles investigated. Copyright
