Synthesis of a cisplatin derivative from lithocholic acid
A new steroidal-platinum(II) hybrid compound was synthesized using a simple and efficient methodology. The synthesis was performed by a convergent approach with cross metathesis (CM) as a key step. An olefin derived from lithocholic acid and a vinyl substituted ethylenediamine derived from L-serine were used as chiral building blocks, which were combined in the CM step. The most important advantage of this method was the utilization of L-serine as a cheap, stereoisomerically pure substrate. A steroid with a diamino system in the side chain was subjected to reaction with potassium tetrachloroplatinate to obtain the target platinum(II) complex. Attempts to synthesize similar diamine systems using the asymmetric Strecker reaction were unsuccessful.

Regioselective glycosylation of fully unprotected methyl hexopyranosides by means of transient masking of hydroxy groups with arylboronic acids
Facile, one-pot synthesis was developed for several β(1→2)-, β(1→3)- or β(1→4)-linked disaccharides from fully unprotected methyl hexopyranosides according to the molecular recognition by arylboronic acids. The methodology was successfully applied to faci

Synthesis and utilization of saccharide intermediates
A new method has been developed for preparation of partially pivaloylated saccharides in one step from readily available starting materials. These intermediates were used in the synthesis of disaccharides and a glucosteroid.

Carbohydrates as Chiral Templates: Stereoselective Strecker Synthesis of D-α-Amino Nitriles and Acids Using O-Pivaloylated D-Galactosylamine as the Auxiliary
The asymmetric synthesis of N-galactosyl D-α-amino nitriles is accomplished by application of 2,3,4,6-tetra-O-pivaloyl-β-D-galactopyranosylamine (4) as the stereodifferentiating template in Strecker reactions.Aldimines 6 derived from 4 and aromatic or ali
