Methods include the method for the preparation of a compound of formula (I): comprising treating a compound of formula (II): with a transition metal catalyst under alkylation conditions.
摘要:
The present invention relates to a coupling method between intramolecular carbon using the intramolecular cyclization reaction in situ of an allyl-indium compound derived from an allyl derivative containing an unsaturated hydrocarbon compound and indium, in presence of a transition metal compound catalyst. More particularly, the present invention relates to a coupling method between intramolecular carbon for preparing a cyclic compound having a vinyl group as a substituent by bonding a carbon in an allyl derivative containing an unsaturated hydrocarbon compound and a carbon in the unsaturated hydrocarbon compound via intramolecular cyclization reaction in situ of an allyl-indium compound as a coupling agent derived from the allyl derivative containing the unsaturated hydrocarbon and indium (In), in presence of a palladium catalyst.

摘要:
3,2-Benzoxazepines of the formula ##STR1## and their preparation. In formula (I), R respesents hydrogen or lower alkyl; R.sup.1 represents hydrogen, lower alkyl, lower alkenyl, hydroxy-lower alkyl, carbamyloxy-lower alkyl, acyl, amidino, carbamyl, mono- or di-substituted carbamyl; R.sup.2 may be in position 7 or 8 of the benzoxazepine ring and represents hydrogen, nitro, amino, acetamino or halo. The compounds are prepared by reacting 1,2,4,5-tetrahydro-3,2-benzoxazepine with a reactant which reacts with a secondary amino group to give substitution in the 2-position. The compounds have anti-inflammatory and central nervous system activity.
