On page 2257, in Table 1, last column: 2A/3A should read 2a/3a. On the same page, right column, in the 4th and the last line from the bottom: 5-exo-dig should be deleted and E-product 2 should be changed to product 2.
In Refences and Notes section compounds 2a-i should be correctly named as follows:
2a: 4-Phenyl-3-(prop-1-en-2-yl)-1-tosyl-1,2,3,6-tetrahydropyridine
2b: 1-(Mesitylsulfonyl)-4-phenyl-3-(prop-1-en-2-yl)-1,2,3,6-tetrahydropyridine
2c: 4-Phenyl-3-(prop-1-en-2-yl)-3,6-dihydro-2H-pyran
2d: 4-Methyl-3-(prop-1-en-2-yl)-1-tosyl-1,2,3,6-tetrahydropyridine
2e: 4-Cyclopropyl-3-(prop-1-en-2-yl)-1-tosyl-1,2,3,6-tetrahydropyridine
2f: 4-Cyclohexenyl-3-(prop-1-en-2-yl)-1-tosyl-1,2,3,6-tetrahydropyridine
2g: 4-(4-Methoxyphenyl)-3-(prop-1-en-2-yl)-1-tosyl-1,2,3,6-tetrahydropyridine
2h: 4-(Naphthalen-1-yl)-3-(prop-1-en-2-yl)-1-tosyl-1,2,3,6-tetrahydropyridine
2i: 4-(3,5-Dimethylphenyl)-3-(prop-1-en-2-yl)-1-tosyl-1,2,3,6-tetrahydropyridineFigure
1 should be replaced by the X-ray crystal structure shown below:

Some signals in the 1H NMR data of compounds 1e,f and 2a,e were incorrectly assigned; the corrected values should read as follows:1e: 7.69 (d, J = 8.3 Hz, 1 H) Æ 7.69 (d, J = 8.3 Hz, 2 H).1f: 7.74 (d, J = 8.3 Hz, 1 H) Æ 7.74 (d, J = 8.3 Hz, 2 H).2a: 4.78 (s, 3 H), 4.88 (s, 3 H) Æ 4.78 (s, 1 H), 4.88 (s, 1 H).2e: 0.45 (m, 1 H), 0.56 (m, 1 H), 1.20 (m, 2 H) Æ 0.21 (m, 1 H), 0.45 (m, 1 H), 0.56 (m, 2 H), 1.20 (m, 1 H); 7.30 (d, J = 8.5 Hz, 1 H), 7.64 (d, J = 8.3 Hz, 1 H) 7.30 (d, J = 8.5 Hz, 2 H), 7.64 (d, J = 8.3 Hz, 2 H).The authors apologize for the above mistakes.
