large strong-field increment for 2-CH~ was observed here, and the chemical shift for this carbon atom is 14.5 ppm, whereas it was more than 19.8 ppm in all other cases. A "~ effect" in this case is clearly observed not only for C(s ) but also for C(~) and C(6 ) (Table 3). The substantial dependence

The heat effectsof the elementary processes involved in electron and hydrogen transfer with the participation of 1,4-dihydropyridines were calculated by the semiempirical MINDO/3 method. The effect of a number of side and parallel processes on the kinetic principles is discussed in the case of the o

New derivatives of 3,4-dihydrospiro[cycloalkane- \(1^{\prime}, 2(1 H)\)-quinolines] were obtained from cycloheptanone and cyclooctanone via facile three steps hetero spiro annulation process. Their nitro derivatives were prepared through electrophilic substitution reactions.
