, p. 1723 - 1728 (2005)
A simple method for the preparation of both enantiomers of tetra-O-benzyl-myo-inositol is presented. This method is based on the resolution of stereoisomers by crystallisation. Starting with the known synthesis of four diastereomers using d-camphor dimeth

First, total synthesis of the cell surface phospholipomannan anchor [β-Manp-(1 → 2)-β-Manp]n-(1 → 2)-β-Manp-(1 → 2)-α-Manp-1 → P-(O → 6)-α-Manp-(1 → 2)-Inositol-1-P-(O → 1)-phytoceramide of Candida albicans is reported. The target phospholipomannan (PLM) anchor poses synthetic challenges such as the unusual kinetically controlled (1 → 2)-β-oligomannan domain, anomeric phosphodiester, and unique phytoceramide lipid tail linked to the glycan through a phosphate group. The synthesis of PLM anchor was accomplished using a convergent block synthetic approach using three main appropriately protected building blocks: (1 → 2)-β-tetramannan repeats, pseudodisaccharide, and phytoceramide-1-H-phosphonate. The most challenging (1 → 2)-β-tetramannan domain was synthesized in one pot using the preactivation method. The phytoceramide-1-H-phosphonate was synthesized through an enantioselective A3 three-component coupling reaction. Finally, the phytoceramide-1-H-phosphonate moiety was coupled with pseudodisaccharide followed by deacetylation to produce the acceptor, which on subsequent coupling with tetramannosyl-H-phosphonate provided the fully protected PLM anchor. Final deprotection was successfully achieved by Pearlman's hydrogenation.
N-heterocyclic carbene-catalyzed benzoin strategy for divergent synthesis of cyclitol derivatives from alditols

A divergent synthesis of cyclitol derivatives has been developed utilizing an N-heterocyclic carbene-catalyzed benzoin-type cyclization of C2-symmetrical dialdoses. The resulting inososes are versatile intermediates, which are readily converted
