Abstract
Chitin, abundant biomass found in crab shells and other marine life, has wide applications in the production of food, pharmaceuticals, and cosmetics. Our recent studies have focused on the development of new functional materials by derivatizing chitin oligosaccharides and monosaccharides. For example, we have prepared various derivatives by chemoenzymatic synthesis using N-acetylglucosamine (GlcNAc) or chitin oligosaccharide prepared from chitin as starting materials. First, we have achieved the total synthesis of two secondary metabolites (furanodictine A and B) with neuronal differentiation-inducing activity on PC12 cells by using a simple heatinduced structural transformation of GlcNAc and esterification reaction. Second, we synthesized both a novel inhibitor that has facilitated a re-examination of the reaction mechanism of hen egg-white lysozyme, and a new substrate for assaying lysozyme activity by using chitin oligosaccharides as raw materials. Thus, the development of new materials by simple derivatization of chitin mono- or oligo-saccharides is paving the way for effective use of chitin.

Abstract
The cellular slime mold Dictyostelium discoideum is an excellent model organism for the study of cell and developmental biology because of its simple life cycle and ease of use. Recent findings suggest that Dictyostelium and possibly other genera of cellular slime molds, are potential sources of novel lead compounds for pharmacological and medical research. In this review, we present supporting evidence that cellular slime molds are an untapped source of lead compounds by examining the discovery and functions of polyketide differentiation-inducing factor-1, a compound that was originally isolated as an inducer of stalk-cell differentiation in D. discoideum and, together with its derivatives, is now a promising lead compound for drug discovery in several areas. We also review other novel compounds, including secondary metabolites, that have been isolated from cellular slime molds.

Abstract
A new synthetic approach to (+)-batzellaside B from naturally abundant L-pyroglutamic acid is presented in this article. The key synthetic step involves Sharpless asymmetric dihydroxylation of an olefinic substrate functionalized with an acetoxy group to introduce two chiral centres diastereoselectively into the structure. Heterocyclic hemiaminal 4, which could be converted from the resulting product, was found to provide stereospecific access to enantiomerically enriched allylated intermediate, offering better prospects for the total synthesis of this natural product.
