摘要:
In a short total synthesis of morphinan compounds, derivatives of 1-benzyl-1,2,3,4-tetrahydroisoquinoline are produced. Certain of these compounds, although highly aromatic and functionalized, can be optically resolved. The optically active enantiomers can serve as important intermediates for both natural and unnatural opioids. As a special function of this invention, certain of the derivatives, namely 4'-6' and 7'-9', may be hydrogenated to 1'-3' derivative by asymmetric reduction either of the catalytic or chemical type.
摘要:
This invention relates to compounds which may be described as the unnatural enantiomers of morphine agonists and antagonists, which are useful as antitussives. The synthesis utilized is capable of producing all of the unnatural enantiomers of medically important opium derivatives of the morphinan type, including thebaine.

Certain nitrogen-containing cyclohetero cycloalkylaminoaryl compounds are described for treatment of CNS disorders such as cerebral ischemia, psychotic disorders, convulsions and parkinsonism. Compounds of particular interest are of the formula ##STR1## wherein R.sup.1 is selected from hydrido, loweralkyl, cycloalkylalkyl of four to six carbon atoms and loweralkenylloweralkyl; wherein each of R.sup.2 and R.sup.3 is independently selected from hydrido and loweralkyl; wherein each of R.sup.4 through R.sup.7, R.sup.10 and R.sup.11 is independently selected from hydrido, hydroxy, loweralkyl, benzyl, phenoxy, benzyloxy and haloloweralkyl; wherein n is a number selected from four through six; wherein p is a number selected from zero through four; wherein q is a number selected from three through five; wherein A is selected from phenyl, naphthyl and thienyl; wherein any of the foregoing A groups can be further substituted with one or more substituents independently selected from hydrido, hydroxy, loweralkyl, loweralkoxy, halo, haloloweralkyl, amino, monoloweralkylamino and diloweralkylamino; or a pharmaceutically acceptable salt thereof.
摘要:
Compounds, compositions and methods of treatment are described to control brain damage associated with anoxia or ischemia which typically follows stroke, cardiac arrest or perinatal asphyxia. The treatment includes administration of an N-(1-thienylcycloalkyl)alkenylamine compound as an antagonist to inhibit excitotoxic actions at major neuronal excitatory amino acid receptor sites. Compounds of most interest are those of the formula ##STR1## wherein R.sup.1 is one or more groups selected from hydrido, alkyl of one to about five carbon atoms, cycloalkyl of three to about five carbon atoms, alkenyl of two to about five carbon atoms, hydroxyl and alkoxy; wherein each of R.sup.2 is one or more groups selected from hydrido, alkyl of one to about five carbon atoms, cycloalkyl of three to about five carbon atoms, alkenyl of two to about five carbon atoms, hydroxyl, oxo and alkoxy; wherein R.sup.5 is one or more groups selected from hydrido, alkyl of one to about five carbon atoms, cycloalkyl of three to about five carbon atoms, alkenyl of two to about five carbon atoms, hydroxyl and alkoxy; and wherein the broken line within the N-containing ring represents a double bond between any two adjacent carbon atoms

摘要:
A derivative of phencyclidine (1) bearing an isothiocyanate moiety on the meta position of the aromatic ring (3; Metaphit as methanesulfonate and HCl salt) has been synthesized and identified as a rapid and specific site-directed acylating agent of the [.sup.3 H]-phencyclidine binding site in rat brain homogenates. Additional related compounds to Metaphit are Thiophit (oxalate salt), Ethylphit (HCl salt), and Isopropylphit (HCl salt).
