- Ultrafast Photoclick Reaction for Selective18F-Positron Emission Tomography Tracer Synthesis in Flow
-
The development of very fast, clean, and selective methods for indirect labeling in PET tracer synthesis is an ongoing challenge. Here we present the development of an ultrafast photoclick method for the synthesis of short-lived18F-PET tracers

- Preparation of polycyclic azaarenes by an extended Pomeranz-Fritsch procedure
-
An extension of the Pomeranz-Fritsch procedure has been evaluated as a route to some polycyclic azaarenes. Aromatic aldehydes were treated with the dimethyl and diethyl acetals of 2-aminoethanal, the resulting imines reduced to amines which were tosylated and the resulting sulfonamides treated under a range of acidic conditions. The two naphthaldehydes led to benzo[f]isoquinoline and benzo[h]isoquinoline in overall yields of 13% and 36%. Phenanthrene-9- carbaldehyde and phenanthrene-3-carbaldehyde gave dibenzo[f,h]isoquinoline and naphtho[2,1-g]isoquinoline, respectively, as the major tetracyclic products. No pentacyclic product was obtained from a similar sequence starting from pyrene-1-carbaldehyde. Georg Thieme Verlag Stuttgart.

- Synthesis and separation of the atropisomers of 2-(5-benzo[b]fluorenyl)-2′-hydroxy-1,1′-binaphthyl and related compounds
-
Several syn and anti atropisomers of 2-(5-benzo[b]fluorenyl)-2′-hydroxy-1,1′-binaphthyl and related compounds were synthesized from 1,1′-binaphthyl-2,2′-diol (BINOL). It was possible to separate the syn and anti atropisomers by silica gel column chromatog

- A general method for the alkaline cleavage of enolisable ketones
-
An efficient method is described for the cleavage of enolisable aryl methyl and aryl ethyl ketones using an excess of KOH in DMF at an elevated temperature. It presents a general hydrolytic method yielding aromatic carboxylic acids, and is complementary to the widely used oxidative methods for ketone cleavage.
