Abstract

Synthesis of New Trialkylsilylmethyloxazinones via IntramolecularTrapping of β-Silyl Carbocations by an N-Boc Group.-Allylation of N-Boc protected amino ethers with silanes (II) and (VI) is investigated with the view to preparing allylated derivatives of type (VIII). However, a new reaction leads to silylated oxazinones as the major or sole products depending on the substitution pattern of the starting silane. -(BROCHERIEUX-LANOY, S.; DHIMANE, H.; POUPON, J.-C.; VANUCCI, C.; LHOMMET, G.; J.
