Design and synthesis of (2R,3S)-iodoreboxetine analogues for SPECT imaging of the noradrenaline transporter
摘要:
A stereoselective 10-step synthesis of iodophenoxy analogues of (2R,3S)-reboxetine has been developed with the aim of generating a new SPECT imaging agent for the noradrenaline transporter (NAT). In vitro testing of these compounds against various mono-amine transporters showed an ortho-iodophenoxy analogue to have excellent affinity (K-i 8.4 nM) and good selectivity for NAT.

Reaction of enantiopure epoxides (1) with NO occurred highly stereoselectively, affording syn-ring opened products, nitrates (2). The configuration of 2 was confirmed to be retained by determining the configuration of reduced products 1,2-glycols (4) from 2. A possible mechanism is suggested to trace out the syn-ring opening pathway.
Tire asymmetric dihydroxylation (AD) of primary allylic halides is described. Enantiomeric excesses range from 40 to 98%. Subsequent base treatment gives epoxy alcohols in high yields. This strategy is further illustrated by the synthesis of (-)-diepoxybutane, an important C-4-chiral building block.
