In situ generated aza-diene, from N-[methyl-N-(trimethylsilyl)methyl]aniline in the presence of a catalytic amount of molecular iodine undergoes smooth [4+2] cycloaddition with electron-rich enol ethers, such as 3,4-dihydro-2H-pyran and 2,3-dihydrofuran under mild and neutral conditions to afford th
