This article describes the design, optimisation and development of a Suzuki cross-coupling protocol mediated by an efficient palladium-encapsulated catalyst (Pd EnCat) under microwave irradiation. The methodology has been used in both batch mode for classical library preparation and in continuous-flow applications furnishing multigram quantities of material. Described is a method that uses direct focused
[Subject]
The present invention has a purpose for providing a PPAR γ modulator which can be a therapeutic agent for retrograde osteoporosis in which excessive differentiation of adipocytes was inhibited and formation and differentiation of osteoblasts from stem cells is facilitated or that for diabetes mellitus without characteristics such as excessive adipogenesis, liver dysfunction, vascular disorders, heart diseases and the like.
[Solution]
A compound of the following formula or a pharmacologically acceptable salt thereof:
wherein A represents a phenyl group or the like, B represents an aryl group or the like, X represents an oxygen atom or the like, and n represents 0 or 1.
