General routes for the synthesis of 1,3-oxazin-4-ones are discussed, with particular
attention paid to recent developments in the field. The syntheses of amine functionalised
cyclopropyl carbinols via a hydride-mediated reduction of various 5-chloroethyl-1,3-oxazin-4-enones
in moderate to good yield are disclosed. This new method provides an opportunity to
access greater structural diversity within these useful synthetic building blocks.
