Disalicylic acid derivatives with stilbene and bis-styrylbenzene skeleton were synthesized as PTP1Binhibitors. The most potent in this series exhibited a submicromolar IC(50) value. One of the compounds 7b was tested in an animal model for its efficacy as an anti-diabetic or an anti-obesity agent. In feeding compound 7b to diet-induced obese mice, no significant differences in weight gain and food
First Stepwise Dötz Reaction: Isolation and Characterization of a Chelated Metallatriene Intermediate. Influence of Its Pattern of Substitution in Product Partition
substitution. Thermal decomposition of carbenes 9 produced either cyclopentadienes 13 or phenol derivatives 15, the major products in the Dotz reaction, thus demonstrating that they can be the actual intermediates in this reaction. The overall process can be considered a Dotz reaction carried...
