    Remote steric effect on the regioselectivity of Sharpless asymmetric dihydroxylation
    摘要:
    Studies on the regioselectivities for the Sharpless asymmetric dillydroxylation (AD) of conjugated dienoates, trienoates, dienones and dienamides are described. Excellent regioselectivities were obtained in straight chain dienoates, all trienoates, ketones damicles. The remote branched iso-propyl and tert-butyl groups of dienoates greatly lowered the normally excellent regiocontrol. This observation is rationalized in terms of substrate conformational changes, and the steric interaction between the branched methyl group of iso-propyl ortertbutyl groups and the ethyl group Oil the (DHQD)(2)PHAL ligand.

    approach to the synthesis of the naturally ubiquitous syn deoxypropionate motif is reported. The route comprises a new Horner–Wadsworth–Emmons reagent to prepare α,β,γ,δ-bisunsaturated thioesters. Next, two Me-substituents are introduced in high yield, regio- and enantioselectivity using sequential asymmetric Cu-catalyzed 1,6-conjugate addition, base-catalyzed olefin isomerization and Cu-catalyzed enantioselective
