Y(OTf)3-catalyzed addition reaction of alcohol to β-nitrostyrene.

A concise and efficient addition reaction of alcohol to β -nitrostyrene promoted by Y(OTf) 3 has been established for the synthesis of β -nitroether derivatives. The present approach shows attractive properties, such as the high efficiency of catalyst, operational simplicity, and the tolerance of a wide range of functional groups. This strategy not only provides a variety of β -nitroethers but also expands the scope of application of early transition metals. [ABSTRACT FROM AUTHOR]
