Following are structural formulas for 1,4-dioxane and piperidine. 1,4-Dioxane is a widely used solvent for organic compounds. Piperidine is found in small amounts in black pepper Piper nigrum). [Pg.147]

Treatment of ethyl acetoacetate with acetaldehyde in the presence of the base piperidine was found to give a product of formula Ci4H220<5. Controversy arose about its structure did it have open-chain structure III or cyclic structure IV, each formed by combinations of aldol and Michael condensations ... [Pg.882]

Isolated by Arata and Ohashi (3S) from the rootstock of N. japonicum and found to have the empirical formula C15H23O2N, nuphamine proved to be an alkaloid incorporating piperidine and furan rings and to have structure LIV. [Pg.461]

Huperzine B has a molecular formula of C16H20N2O, m.p. 270-271 °C, [cx]d-54.2° (C, 0.2, MeOH). It has UV spectrum absorptions at Amax (log e) 231 (3.95), 312 (3.85), and IR spectrum absorptions at vmax 3100, 1670, 1620,1610,1560 cm-1. The whole structure was proposed by spectral analyses as shown in 5-3. Its main difference from huperzine A is the absence of exocyclic double bond which form an additional piperidine ring in 5-3. Huperzine B does not possess anticholinesterase activity. [Pg.748]

Most of the congeners of thalmine, C20H23O3N (see Volume V, p. 325), are aporphines but this alkaloid proved to be the first of a new structural type. There are two methoxyls in the molecule and the third oxygen is present as hydroxyl. Acetylation yields a neutral 0,V-diacetyl derivative and Hofmann degradation yields in two stages a compound formulated as LXXXVI (mp 212°). This on oxidation generates 5,6 -dimethoxydiphenic acid which is also obtained by oxidation of the alkaloid. Reduction of LXXXVI leads to the formation of a dihydro derivative (mp 173°) which on oxidation yields the diphenic acid as well as propionic acid. The proposed structure (LXXXV) accounts for these reactions but equally satisfactory would be one in which the piperidine nucleus is inverted with the nitrogen at the top in the formula (231).
