2-Ethoxy-3,4-dihydro-2H-pyran-6-carbonitriles are obtained in high yield by stereospecific endo-mode cycloadditions of ccJ-unsaturated acyl cyanides and ethyl vinyl cther at room temperature. The nitrile group is converted to some other functionalities.
## Abstract The hetero Diels‐Alder reactions of enamino ketones 1 and 2 with the vinyl ethers 3–5a are studied in dichloromethane solution under high pressures up to 5 kbar. The kinetics is measured by on‐line FT‐IR spectroscopy to 3 kbar. The cycloaddition reactions of enamino ketones 1 and 2 with
