The PMR spectra of diacetates XI and XVII show the 4-H proton signals at 5.20 and 5.25 ppm, and those of diacetates XXII and XXIII show the corresponding signals at 4.58 and 4.56, respectively, as 17 Hz wide quartets due to their axial orientation. On the contrary, the PMR spectra of acetates XXIV and XXV show the 4-H proton signals at 4.88 and 4.94 ppm,(More)
Cinnamoyl oxiranes (Ia-h) are condensed by known methods with methyland benzylamines to give the C(3)-stereoisomeric, 6-aryl-substi tuted 3e-hydroxypiperidin-4-ones (II-IX) [2] and 3a-hydroxypiperidin-4-ones (X-XIV) [3] (see Table 1). Their physical constants and spectral data correspond with l i terature values [2, 3]. Thus, the PMR spectra for the(More)
