Synthesis of substituted 2,3-dihydro-1H-boroles by transmetalation of aluminacyclopent-2-enes with BF3·Et2O

A procedure was developed for selective synthesis of 4,5-dialkyl-1-fluoro-2,3-dihydro-1 H -boroles via transmetalation of the corresponding aluminacyclopent-2-enes with BF 3 ·Et 2 O. 4,5-Dialkyl-1-fluoro-2,3-dihydro-1 H -boroles were isolated as complexes with BEtF 2 . 4-Alkyl-5-dimethylaminomethyl-...

Description
Summary:A procedure was developed for selective synthesis of 4,5-dialkyl-1-fluoro-2,3-dihydro-1 H -boroles via transmetalation of the corresponding aluminacyclopent-2-enes with BF 3 ·Et 2 O. 4,5-Dialkyl-1-fluoro-2,3-dihydro-1 H -boroles were isolated as complexes with BEtF 2 . 4-Alkyl-5-dimethylaminomethyl-1-fluoro-2,3-dihydro-1 H -boroles were synthesized for the first time.
