A novel one-step construction of bicyclo[5.3.1]undecane skeleton via intramolecular cycloaddition of allenyl ethers is described.
Competitive intramolecular [4 + 2] cycloaddition and tandem [2 + 2] cycloaddition/ [3,3]-sigmatropic rearrangement sequence of allenyl 3-vinyl-2-cyclohexenyl ethers: evidence for switching of the reaction pathway by the substituent effects
Les reactions de cycloaddition de (propargyl vinyl-3 cyclohexene-2yl) ethers passent par des intermediaires (allenyl vinyl-3 cyclohexene-2yl) ethers, isoles dans certains cas
