Allylindium and allylboronic acid pinacolate: Mild reagents for the allylation of resin-bound aldehydes. Application to the solid-phase synthesis of hydroxypropylamines

Homoallylic alcohols are prepared in high yield and puritY by the reaction of the title reagents with resin-bound aldehydes. The mild reaction conditions accommodate the base-sensitive 4-carboxamido-3-nitrobenzyl photolabile linker on standard resins. A p

Palladium-catalyzed formation and stereoselective isomerization of 5- vinyloxazolines. Application to the formal synthesis of (S,S)-4-amino-3- hydroxy-5-phenylpentanoic acid

Vinyloxazolidinones have been found to undergo Pd(0)-catalyzed ionization followed by loss of carbon dioxide and subsequent cyclization to form vinyloxazolines. The reaction occurred under mild conditions, and enhancement of diastereomeric ratios with chiral substrates was obtained. 4- Benzyl-5-vinyloxazoline prepared by this method has been utilized in the stereoselective synthesis of (S,S)-4-amino-3-hydroxy-5-phenylpentanoic acid (AHPPA).

A NEW MODE OF CYCLIC CARBAMATE FORMATION VIA tert.-BUTYLDIMETHYLSILYL CARBAMATE. STEREOSELECTIVE SYNTHESES OF STATINE AND ITS ANALOGUE

Stereoselective construction of 1,2- and 1,3-amino hydroxyl systems was carried out using SN2' (initiated by AgF or AgF-Pd(II)) cyclic carbamate formations from tert.-butyldimethyl silyl carbamates.This method was applied to the syntheses of st
