The preparation and properties of 3-keto-1,2,5,6-tetrahydro-3(H)-imidazo(1,2-a)imidazole, 3-keto-1,2,6,7-tetrahydro-3(H),5(H)-imidazo(1,2-a)pyrimidine, and 4-keto-2,3,6,7,8,9-hexahydro-4(H)-pyrimido(1,2-a)pyrimidine are described. The first two bicyclic systems possess active methylene groups in position 2 and they are oxidized to indigo-type dyes.
Iminium carbonic acid derivative salts.<b>IX</b>. Synthesis of<i>N,S</i>-containing heterobicycles from<i>N</i>-protected 2-methylthio-1,3-thiazinium and 2-methylthiothiazolium salts part 1. Preparation of<i>N</i>-protected 2-methylthio-1,3-thiazinium and 2-methylthiothiazolium salts and their reaction with CH-acidic compounds
by methyl iodide or trimethyloxonium tetrafluoroborate. This activated species were reacted with CH-acidic compounds forming ketene-N,S-acetals. The protection group was removed with trifluoracetic acid to yield the N-unsubstituted ketene-N,S-acetals.
reaction with a range of organoboryl and organostannyl re- agents to produce 2-aryl- or 2-hetaryl-substituted oxazolines. Pro- tected and unprotected carbohydrate backbones were shown to be compatible with the reaction conditions. This approach opens a new versatile access to chiraloxazoline structures. The broad applicability of palladium-catalyzed carbon- carbon bond formation stems from the effectiveness
