چکیده
An improved and scalable synthesis of the unsubstituted 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene framework facilitates access to the previously unreported parent dipyrrin HCl salt, as well as 4,4-dichloro-4-bora-3a,4a-diaza-s-indacene.

متن کاملAxially chiral BODIPYs.
The synthesis and resolution of a class of chiral organic fluorophores, axially chiral 4,4-difluoro-4-bora-3a,4a-diaza-s-indacenes (Ax*-BODIPY), is described. Ax*-BODIPYs were prepared through a modular synthesis combined with a late stage Heck functionalisation. Resolution was achieved by preparative chiral HPLC. Absolute stereochemical assignment was performed by comparison of experimental EC...

Progesterone, 17-hydroxyprogesterone and four other 3-keto steroids were determined by high performance liquid chromatography with fluorescence detection. Each steroid was derivatized with 4,4-difluoro-5,7-dimethyl-4-bora-3a,4a-diaza-s-indacene++ +-3- propionohydrazide (BODIPY FL hydrazide) and separated on a Wakosil 5C4 column with acetonitrile-water (7 + 3) as mobile phase. The limits of dete...
