Abstract

Stereospecific functional group conversions of nonracemic alcohols and diols and their derivatives are of increasing importance given the powerful catalytic asymmetric reactions available for their synthesis. If neighboring-group participation [1] and metal-catalyzed allylic substitution [2] are excluded, there are exceedingly few reports of nucleophilic displacement reactions on unactivated saturated carbon leading to products with a high degree of ...
