The high-pressure promoted cycloadditions of enol ethers (1) and alkyl 3-aryl-2-cyano-2-propenoates (2) lead stereoselectively in high yields to 2,6-dialkoxy-4-aryl-3,4-dihydro-2Hpyran-5-carbonitriles (3). These cycloadducts have a high potential for further synthesis due to the presence of various
Tandem [4+2]β’[3+2] cycloadditions of nitrostyrene and I-phenyl-2-nitropropene with ethyl vinyl ether or 2,3-dihydrofuran are strongly accelerated under high pressure. Mono 14+2] cycloadducts and tandem [4+21/[3+2] cycloadducts were obtained. Furthermore, the in sttu formed mono adduct reacts selecti
