3‐dipolar cycloadditions of non‐stabilized azomethine ylides with diversely substituted 2‐pyridone systems, bearing two potential C=C dipolarophilic sites was reported. The TFA‐catalyzed cycloadditions involving the in situ prepared electron‐rich 1,3‐dipole are studied according to the nature of pyridone substituents. These reactions occur in mild conditions, good yields, and show a full control of the
The present invention relates to methods for generating mature insulin-producing β-like cells comprising the steps: (a) isolating, purifying and/or enriching β-cell progenitor cells from a population of cells; (b) differentiation of the β-cell progenitor cells into immature insulin-producing β-like cells; and (c) maturation of the immature insulin-producing β-like cells into mature insulin-producing β-like cells, comprising exposing the immature insulin-producing β-like cells to calcitriol or an analogue thereof. More particularly, the present invention relates to methods for generating mature insulin-producing β-like cells for use in treating diabetes.
