Irradiation (u>345 nm) of catalytic amounts of 2,4,6-triphenylpyrylium tetrafluoroborate (TPT) in a CH 2 Cl 2 solution of N-aryl imines and a-methylstyrene or styrene produced the corresponding [4+2] cycloaddition products, tetrahydroquinoline derivatives, in good yield. The reaction was controlled
## Abstract The tandem Knoevenagel hetero Diels‐Alder reaction of 4,4,4‐trichloro‐3‐oxobutanal (4), the malondialdehyde derivative 11a, and the enol ether 13 was followed by separation of the diastereomers and treatment with DBU in methanol. Thermolysis in xylene then gave the secologanin derivativ
