Publikováno v: Molecules, Vol 12, Iss 9, Pp 2089-2105 (2007)

The aqueous tin-mediated Barbier reaction affords good to excellent yields and moderate syn diastereoselectivity under basic and acidic conditions. The high yields and stereoselectivity observed in the case of o-substituted aldehydes suggest a cyclic
