We describe two applications of silicon-tethered thermal allyl transfer reactions of α-silyloxyaldehydes; formally, these processes can be regarded as silatropic carbonyl enereactions in which the silicon tether is transferred to the aldehyde oxygen concurrent with carbonyl allylation. In the first application, isoserinal substrates, which bear side-chain nitrogen functionality, are elaborated to
