Trioxo ester 15 was prepared by attachment of two vicinal C-16 regioselectively in one operation. Deprotection of 16 afforded the antibiotic G-2A (1) and decarboxylation of 1 4 and C-6 ketide side chains on the anthraquinone core (6b). Mild base treatment of 15 initiated successive aldol lead to G-2

Methods for the synthesis of each of the four stereoisomers of 6-(3propylthio-1,2,5-thiadiazol-4-yl)-1-azabicyclo[3.2.1]octane (10, 11, 12, and 13) and 3-(3-propylthio-1,2,5-thiadiazol-4-yl)-1-azabicyclo[2.2.1]heptane (18, 19, 20, and 21), and the two stereoisomers of 3-(3-propylthio-1,2,5-thiadiazo
Some polyimide films based on cyclobutane-1,2,3,4-tetracarboxylic dianhydride (CBDA) and aromatic diamines were synthesized to investigate their temperature resistance and percent transmission of light. The preparations of CBDA were investigated; they produced almost 10 times the yield of CBDA in co
