(4S-TRANS)-2 2-DIMETHYL-A A A' A'-TETRA& Chemical Properties,Usage,Production
Uses
(4S-trans)-2,2-Dimethyl-α,α,α′,α′-tetra(1-naphthyl)-1,3-dioxolane-4,5-dimethanol, also known as TADDOL, is a chiral auxiliary that can be used:
- For the highly enantioselective addition of primary alkyl Grignards to ketones.
- As an organocatalyst for the activation of carbonyl functionality in vinylogous addition reaction of an aldehyde.
- As a chiral dopant in the preparation of cholesteric liquid crystal (CLC) having an aggregation-induced-emission dye.
