Abstract (en)
[origin: DE3047759A1] Method of preparation of //c<s2>s N-heterocycles having the general formula I (FORMULA) wherein v is an integer from
1 to 4, R<u1>u represents (if v = 1) hydrogen, one of the following residues: alkyl with 1 to 19 carbon atoms, aralkyl with 7 to 10 carbon atoms or
cycloalkyl with 5 to 7 carbon atoms, these residues being optionally substituted by hydroxy, amino, nitro, fluorine, chlorine, bromine, C<u1>u-C<u4>u
alkoxycarbonyl, di-C<u1>u-C<u4>u alkylaminocarbonyl, C<u1>u-C<u4>u alkylaminocarbonyl, tri-C<u1>u-C<u4>u alkylsilyloxy, tetrahydropyranyloxy
or benzyloxy; or one of the oxo-alkyl with 1 to 6 carbon atoms, aryl residues or an heterocycle having 5 to 6 links with 1 to 3 nitrogen, oxygen or
sulphur atoms as heteroatoms; R<u1>u represents (if v = 2) an arylene residue, an alkylene - (CH<u2>u)-<um>u residue, wherein m is 1 to 6, and
which may be substituted by hydroxy, oxo, amino, nitro, fluorine, chlorine, bromine, tri-C<u1>u-C<u4>u alkylsilyloxy, or benzyloxy; or the -CH =
CH- residue; R represents (if v = 3 or 4) a benzene residue with 3 to 4 free valences or an alkylene - (CH)- residue with 3 to 4 free valences, which
may optionally be substituted by hydroxy, oxo, amino, nitro, fluorine, chlorine, bromine, tri-C<u1>u -C<u4>u alkylsilyloxy, tetrahydropyranyloxy, or
benzyloxy; D represents an imino residue or a direct link; Y represents an oxygen or sulphur atom, or an imino residue or N-(C<u1>u-C<u4>u alkyl)imino; Z represent the (CR<u6>uR<u7>u)<un>u residue wherein n may be 0 to 3; R represents a hydrogen atom, an alkyl residue with 1 to 6 carbon
atoms, optionally substituted by hydroxy or amino; or a C<u1>u-C<u4>u alkoxycarbonyl, cyano or di-C<u1>u-C<u4>u alkylaminocarbonyl residue,
R<u3>u, R<u4>u, R<u5>u, R<u6>u, R<u7>u each represent a hydrogen atom, an alkyl residue with 1 to 6 carbon atoms, optionally substituted
by hydroxy or amino; or an aryl residue; R<u3>u and R<u4>u represent together a trimethylene, tetramethylene or 1, 3-butadienylene residue, to
the extent that R and R represent together a direct link; this method utilizing as starting compounds those having the general formula (FORMULA)
wherein R<u1>u, D and v have the above-mentioned meanings, and X represent an oxygen or sulphur atom or the residue (FORMULA) R<u8>u
represents hydroxy, a C -C alkoxy residue, a C<u1>u-C<u6>u alkylthio residue, an aryloxy or arylthio residue, an aralkyloxy or aralkylthio residue
with 7 to 10 carbon atoms, a C<u1>u-C<u4>u trialkylsilyloxy or C<u1>u-C<u4>u trialkylaralkylsilythio residue; this method utilizing as starting
compounds also the amines of general formula (FORMULA) wherein R<u2>u R, R<u4>u, R<u5>u, Y and Z have the above-mentioned meanings;
that method is characterized by the fact that the reaction is carried out by means of organic phosphines or of phosphonium salts and perhalogenated
hydrocarbons or ketones respectively with azodicarboxylic acid diesters in the presence of tertiary amines.
