Abstract The efficient deprotection of several acetals, dithioacetals, and tetrahydropyranyl (THP) ethers under ambient conditions, using chloral hydrate in hexane, is described. Excellent yields were realized for a wide range of both aliphatic and aromatic substrates. The method is characterized by mild conditions (room temperatures or below), simple workup, and the ready availability of chloral hydrate. High chemoselectivity was also observed in the deprotection, acetonides, esters, and… 
Chloral Hydrate as a Water Carrier for the Efficient Deprotection of Acetals, Dithioacetals, and Tetrahydropyranyl Ethers in Organic Solvents.
A novel method for the selective deprotection of acetals, dithioacetals and Thp-ethers under mild and neutral conditions is developed.
Utilization of hexabromoacetone for protection of alcohols and aldehydes and deprotection of acetals, ketals, and oximes under UV irradiation
Hexabromoacetone (HBA) was efficiently used for the protection of alcohols and aldehydes and deprotection of benzaldehyde dimethyl acetal, solketal, and other acetals and ketals. In only 10 min, the
Photochemically-assisted synthesis and photophysical properties of difluoroboronated β-diketones with fused four-benzene-ring chromophores, chrysene and pyrene.
TLDR
It was found that PyB is fluorescent, whereas the fluorescence quantum yields of the ChBs depend on the substituted position of the chrysene moiety, which is shown to be of a charge-transfer character.
Synthesis of Chiral Ligands on the Basis of 1-(Adamantan-1-yl)ethane-1,2-diamine
Abstract The reduction of 1-(adamantan-1-yl)-2-azidoethan-1-one oxime with LiAlH 4 gave racemic 1-(adamantan-1-yl)ethane-1,2-diamine, which was resolved with l-tartaric acid. The individual
