Dihydrocodeinone oxime (1) under Beckmann rearrangement conditions gave a product (2) that facilitated the preparation of (-)-11 alpha-substituted 1,2,3,4,5,6-hexahydro-6 alpha,7-(methyleneoxy)-2,6-methano-3-benzazocines, a hitherto little-examined series of morphine partial structures. Compounds 7a and 12 gave good levels of agonist antinociceptive(More)
The synthesis of 4-alkyl-, 4-aralkyl-, and 4-alkenyl-1,2,3,4,5,6-hexahydro-2,6-methano-3-benzazocines is described together with some 4,4-disubstituted and 8-hydroxy derivatives. Evidence of the stereochemistry of the 4-substituent was from 1H and 13C NMR. In the 4-methyl series the equatorial epimer 1b has a higher analgesic (hot-plate) potency than 1a,(More)
INTRODUCTION Aquatic treadmills are used as a rehabilitation method for conditions such as spinal cord injury, osteoarthritis and stroke, and can facilitate an earlier return to exercise training for athletes. However, their effect on cerebral blood flow (CBF) responses has not been examined. We tested the hypothesis that aquatic treadmill exercise would(More)
