Synthesis of Trialkylsiloxy-Substituted and other 5,6-Dihydro-4H-1,2-oxazines by Hetero Diels-Alder Reactions of Nitroso Alkenes - Preparative Scope and Diastereoselectivity

Hippeli, Claudia,Reissig, Hans-Ulrich

, p. 217 - 226 (2007/10/02)

A variety of 5,6-dihydro-4H-1,2-oxazines 3 and 4 is prepared in good yields from silyl enol ethers 1 and nitroso alkenes 2a or 2b, respectively.A systematic variation of substitutens reveals preparative scope and limitations of this hetero Diels-Alder rea
