Discovery of a potent, highly selective, and orally efficacious small-molecule activator of the insulin receptor

A series of 3,6-diaryl-2,5-dihydroxybenzoquinones were synthesized and evaluated for their abilities to selectively activate human insulin receptor tyrosine kinase (IRTK). 2,5-Dihydroxy-6-(1-methylindol-3-yl)-3-phenyl-1,4-benzoquinone (2h) was identified

Fungal Pigments, 49. - Synthesis of Grevillins and Related 2H-Pyran-2,5(6H)-diones

A convergent synthesis of grevillins 1 starts from diazoesters 6 which are converted into 3-aryl-2-oxopropyl ethyl oxalates 4 via bromoketones 7.Cyclization of 4 leads to pyrandiones 2 which are condensed with aromatic aldehydes to yield 4-aryl-2-benzylid
