A novel 2-substituted-6,7-benzomorphan derivative of the formula: ##SPC1##And its acid addition salts, which are useful as non-addicting analgesics and antitussives and can be prepared by reacting a 2-unsubstituted-6,7-benzomorphan derivative of the formula: ##SPC2##With the reactive derivative of an alcohol of the formula:HOA',optionally followed by elimination of the protective group in the resulting product, wherein R.sub.1 is hydrogen, lower alkyl or acyl; R.sub.2 and R.sub.3 are each lower alkyl; A is lower alkyl, cyano(lower)alkyl, benzoyl(lower)alkyl, ar(lower)alkyl, lower alkenyl or cyclo(lower)alkyl(lower)alkyl; and A' is a group as mentioned in A or benzoyl(lower)alkyl of which the carbonyl group is masked with a suitable protective group.
摘要:
An optically active .alpha.,.beta.-di-phenylethylamine of the formula, ##SPC1##Wherein R.sub.1 and R.sub.2 are each hydrogen or C.sub.1 - C.sub.4 alkyl and m and n are each an integer of 1 to 5, is racemized by heating the optically active amine at a temperature between 100.degree.C and the boiling point of the amine in the presence of a dry Raney nickel catalyst in the atmosphere of inert gas. d-Isomers are more useful than the l-isomers as intermediates of optically active fatty acid amides having cholesterol lowering effects.
摘要:
A pharmaceutical composition consisting essentially of pharmaceutically effective amount of an N-substituted fatty acid amide of the formula, ##EQU1## wherein R is a C.sub.13 - C.sub.25 aliphatic hydrocarbon chain or a C.sub.13 - C.sub.25 hydroxylated aliphatic hydrocarbon chain and RCO-- is other than isostearoyl; R' is d- or l-.alpha.-C.sub.1 - C.sub.4 alkylbenzyl, racemic-, d- or l-.alpha.-C.sub.1 - C.sub.4 alkylbenzyl substituted in the benzene ring with one or two substituents selected from the group consisting of C.sub.1 - C.sub.4 alkyl, C.sub.1 - C.sub.4 alkoxy, halogen and nitro, or racemic-, d- or l-.alpha.-benzylbenzyl; R" is hydrogen; or R' and R" together are cyclohexyl; and when RCO-- is isotearoyl R' is alkyl, alkenyl, cycloalkyl, alkylcycloalkyl, hydroxycycloalkyl, alkoxycycloalkyl, alkylphenyl, hydroxyphenyl, alkoxyphenyl, halogenophenyl, halogen-alkyl-substituted phenyl, halogenoalkyl- and halogen-substituted phenyl, alkoxy- and halogen-substituted phenyl, benzyl, racemic-, d- or l-.alpha.-C.sub.1 - C.sub.4 alkylbenzyl, benzyl substituted in the benzene ring with lower alkyl or lower alkoxy, racemic-, d- or l-.alpha.-benzylbenzyl or hydroxybenzyl, and R" is hydrogen or any one of the groups represented by R', and a pharmaceutically acceptable carrier, which is useful for lowering elevated levels of cholesterol in the blood.
