Aromatic methoxymethyl (MOM) ethers behave differently from aliphatic MOM ethers upon treatment with trialkylsilyl triflate (R3SiOTf) and 2,2′-bipyridyl. The aromatic MOM ethers are first converted to silyl ethers and subsequently deprotected by hy

The tricarboxylic acid (TCA) cycle (or citric acid cycle) is responsible for the complete oxidation of acetyl-CoA and formation of intermediates required for ATP production and other anabolic pathways, such as amino acid synthesis. Here, we uncovered

The synthesis of new N1,N8-diacetylspermidine (DiAcSpd) analogues having a linker with desired functional groups in the methylene skeleton, which have been designed by theoretical calculations, is described. We have also achieved the preparation of D

Acetals are the most useful protecting groups for carbonyl functional groups. In addition to the role of protection, they can also be used as synthons of carbonyl functions. Previously, we developed a chemoselective deprotection and nucleophilic subs

The aldol reaction using aldehyde-derived silyl enolates as nucleophiles with aromatic aldehydes chemoselectively proceeded in the presence of silyl triflate and 2,2'-bipyridyl to produce β-siloxy aldehydes, while the aliphatic aldehydes were comple

A versatile and chemoselective route has been developed for the synthesis of aliphatic fluorinated methyl ethers (ROCH 2 R F ), specifically monofluoromethyl ethers (ROCH 2 F) and trifluoromethylthiomethyl ethers (ROCH 2 SCF 3 ), through pyridinium-t

Recent progress in the chemoselective reduction and alkylation of carbonyl functions using our in situ protection method is described. Methods that enable reversal or control of the reactivity of a carbonyl functional group are potentially useful. Th

The development of a novel chemoselective functionalization can diversify the strategy for synthesizing the target molecules. The perfect chemoselectivity between aromatic and aliphatic aldehydes is difficult to achieve by the previous methods. The a
