Abstract
This Perspective article illustrates the key role of thiazole and triazole in the work carried out in the author's laboratory over three decades and deals with the synthesis of carbohydrate-based bioactive molecules. The first part reports on the development of synthetic strategies exploiting the use of various thiazole-based reagents and the ready conversion of thiazole into the formyl group. After describing the chain elongation of monosaccharides into higher-carbon homologues, the synthesis of target natural and non-natural carbohydrates, or their ultimate precursors, is presented. These include some sphingoids, neuraminic and destomic acids, lincosamine, various 3-deoxy-2-ulosonic acids (KDO, KDN, iso-Neu4Ac), iminosugars (nojirimycin, mannojirimycin, galactostatin) and homoazasugars. Also prepared were the disaccharide subunit of bleomycin A(2) and the side-chain of taxol and taxotere.((R)) The use of 1,2,3-triazole is discussed in the second part of the paper. The service of this heterocycle that is easily formed by the Cu(i)-catalyzed azide-alkyne cycloaddition (CuAAC) is considered in light of its use as a robust linker (a sort of keystone) of complex and diverse molecular architectures. Thus, the assembly of triazole-linked glycosyl amino acids, non-natural nucleotides, 1,6-oligomannosides, sialoside clusters on calixarene platfom via CuAAC is described and the biological relevance of these compounds is discussed in brief.

Abstract
Terminal isopropylidene acetals are selectively cleaved to the corresponding 1,2-diols in good to excellent yields in 6-24 h at room temperature by using the 'HClO4.SiO2' reagent system. Likewise, trityl ethers are readily cleaved to the corresponding alcohols in good to excellent yields within 2-3 h at room temperature. Work-up involves merely filtration of the reagent followed by purification of the crude product.

Abstract
An efficient L-3-deoxy-manno-2-octulosonic acid (L-KDO) aldolase was created by directed evolution from the Escherichia coli D-Neu5Ac (N-acetylneuraminic acid, D-sialic acid) aldolase. Five rounds of error-prone PCR and iterative screening were performed with sampling of 10(3) colonies per round. The specificity constant (kcat/Km) of the unnatural sugar L-KDO is improved to a level equivalent to the wild-type D-sialic acid aldolase for its natural substrate, D-Neu5Ac. The final evolved enzyme exhibits a >1,000-fold improved ratio of the specificity constant [kcat/Km (L-KDO)]/[kcat/Km (D-sialic acid)]. The protein sequence of the evolved aldolase showed eight amino acid changes from the native enzyme, with all of the observed changes occurring outside of the active site. Our effort demonstrates that an enzyme can be rapidly altered to accept enantiomeric substrates with screening of a small population of colonies iteratively toward the target substrate with improved catalytic efficiency. This work provides a method for the synthesis of enantiomeric sugars and for the study of enantiomeric catalysis affected by remote mutations.

Abstract
As a part of synthetic studies on MMP (matrix metalloproteinase)/ADAM (a disintegrin and metalloproteinase) inhibitors, we have preliminarily communicated that azasugar-based compound 1a exhibited a potential inhibitory activity on some metalloprotease-catalyzed proteolytic reactions. To find promising candidates for the topical treatment of psoriasis, we investigated stability in aqueous solution of compound 1a and its derivative 1b and then optimized the P1' substuent (2-5). In the present study, we synthesized novel derivatives of compound 1a and evaluated their inhibitory activity toward MMP-1, -3, and -9, TACE, and HB-EGF shedding, from a viewpoint of versatility of azasugars as a functional scaffold. As a result, it was found that compound 1b demonstrated desirable inhibitory activity as an antipsoriatic agent, and some of the derivatives showed selective inhibitory activity. In addition, it was found that compound 1b exhibited a significant therapeutic effect on a mouse TPA-induced epidermal hyperplasia model. Therefore, compound 1b could become a promising candidate as a practical antipsoriatic agent.

Abstract
A new route to Neu5Ac methyl ester (23) with a readily available sugar D-glucono-delta-lactone as starting material has been developed. A diastereoselective propargylation of alpha-acetamino aldehyde and a subsequent KMnO(4) oxidation of the terminal alkyne served as the key steps.
