A simple carbohydrate-based convergent approach towards the totalsynthesis of herbarumin-I, a 10-membered lactone is described. The key features of the synthetic strategy include Grignard reaction and ring-closing metathesis reaction for the formation of the 10-membered ring and E-olefinic moiety. d-Mannitol has been used as a chiral pool material for the construction of the key fragment.

Stereocontrolled syntheses of D(+)-erythro and L(−)-threo sphingosines are described starting from D-xylose and D-arabinose respectively through acetylenic intermediates 3 and 4, obtained by base induced double elimination of the β-alkoxy chlorides 5 & 13.

A novel stereoselective synthesis of N-Boc-(2S,3S)-3-hydroxy-2-phenylpiperidine was achieved from D-mannitol involving the highly stereoselective addition of phenyl Grignard to an allyl imine (de >98%) and ring-closing metathesis (RCM) in the key steps. (C) 2008 Elsevier Ltd. All rights reserved.
