Nakagome and co-workers effected the successful cyclization of N-ethyl-N-arylaminomethylenemalonates (749) in poly phosphoric acid, prepared from orthophosphoric acid and phosphorus pentoxide in polyphosphate ester (PPE), prepared from phosphorus pentoxide and anhydrous diethyl ether in chloroform in phosphoryl chloride on the action of boron trifluoride etherate on the action of acetic anhydride and concentrated sulfuric acid or on the action of phosphorus pentoxide in benzene [71GEP2033971, 71JHC357 76JAP(K) 18440]. Depending on the work-up process, l-ethyl-4-oxoquinoline-3-carboxylates (750, R1 = Et), l-ethyl-4-oxoquinoline-3-carboxylic acids (750, R2 = H) and 3-ethoxycarbonyl-4-chloroquinolinium iodides (751) were obtained. Only the cyclization of... 

A calculated transition energy used to assess the polarity of a solvent. The solvent ionizing capability directly affects the position of a peak, easily measured, in the ultraviolet region of the spectrum of the complex of an iodide ion with 2-methyl- or l-ethyl-4-carbomethoxypyridinium ion. Water has a Z value of 94.6, ethanol has a value of 79.6, dimethyl sulfoxide s value is 71.1, and benzene has a value of 54. A similar polarity scale, known as x(30) values, is related to the Z value scale Z = 1.41 t(30) -E 6.92. See Solvent Effects...

If there is more than one side chain on the benzene ring the name of each radical is preceded by the postion number on the ring. Examples are 1,3-dimethylbenzene and l-ethyl-4-(l-methylethyl)benzene. Position numbers 1,2-, 1,3-, and 1,4- correspond to the designations ortho - (o-), meta - (m-) and para - (p-).

In 1961, two experiments which provided the basis for deducing the skeleton of enmein were carried out by Kanatomo (75, 16). In the first he obtained l-ethyl-4(3,3-dimethylcyclohexyl)-benzene (II) whose structure was proved by synthesis (75). In the second he isolated retene (III) by selenium dehydrogenation of the material obtained by LiAlH4 reduction of enmein (16). Thus enmein was proved to be a diterpene and a phyllocladene (IV) skeleton was proposed for it (16). Kubota and coworkers (77) deduced the presence of a hemiacetal ring (V) and partial structure (VI), with the lactone function part of a six-membered ring, on the basis of chemical evidence and spectral data of various derivatives, and advanced four formulas including (VII) as possible structures for enmein.
