It has been shown In previous papers that the pivalate of 2-nitro-2-propen-1-ol (NPP, 1), a nitroolefin with allylic leaving group, can be used as a versatile multiple coupling reagent. The present contribution describes the preparation of NPP analogues, substituted in the 1- and/or 3-position of the allylic carbon skeleton. Standard methods of nitroaliphatic chemistry readily provide symmetrically substituted derivatives such as the cyclohexenes (7) and the ...
