Approaches towards the synthesis of fluoro(cyclo)alkylamines
摘要:
The synthesis of fluoro(cyclo)alkylamines 1-amino-6-fluorohexane (1), 1-amino-7-fluoroheptane (2), cis/trans-4-fluorocyclohexylamine (3a,b) and cis-4-fluoromethylcyclohexylamine (4) has been investigated for use as synthons for histamine receptor ligands for use in PET.

Representative esters of methanesulphonic acid were synthesized, and cleaved to form the corresponding fluorides, iodides, and thiocyanates. From this work was developed a convenient laboratory procedure for converting alcohols to fluorides.
Some ω-fluoroalkynes have been prepared and shown to be valuable intermediates in the synthesis of rare long-chain ω-fluoro compounds; successful representative reactions, in all of which the C—F bond remained intact, included Grignard reactions, partial and total catalytic hydrogenation, halogenation, and miscellaneous coupling reactions.
