, p. 2409 - 2412 (2007/10/02)
The essential features of the enantiocontrolled total synthesis of (-)-aspicilin are the strategic use of the photochemical rearrangement of α,β-epoxy diazomethyl ketones to 4-hydroxyalkenoates (Scheme 1) and the stereochemical control of the Sharpless epoxidation, α,ο functionalization of an alkynol using potassium 3-aminopropylamine (KAPA) as acetylene zipper, coupling between C7 and C8 by means of a Wittig reaction and lactonization by using 2,6-dichlorobenzoyl chloride.
Synthesis of Saccharides and Related Polyhydroxylated Natural Products. 1. Simple Alditols
Katsuki, T.,Lee, A. W. M.,Ma, P.,Martin, V. S.,Masamune, S.,et al.
, p. 1373 - 1378 (2007/10/02)
A new approach to sugar synthesis is demonstrated through syntheses of tetritols, pentitols, and hexitols; titanium-catalyzed asymmetric epoxidation and a new selective opening reaction of 2,3-epoxy alcohols play essential roles.
