A facile approach to the synthesis of chiral 2-substituted benzofurans.

Lidia De Luca et al.

The Journal of organic chemistry, 72(10), 3955-3957 (2007-04-11)

An effective route to chiral optically active 2-substituted benzofurans directly from carboxylic acids is reported. This procedure, which allows the preparation of alpha-alkyl-2-benzofuranmethanamines from N-protected alpha-amino acids without sensible racemization phenomena, proceeds in good yields under mild conditions with the
