TOS-BB-1318

New Building-Block is added to TOSLab Building-Blocks database.

The ethyl 5-[(chlorocarbonyl)amino]-1,2,3-thiadiazole-4-carboxylate readily reacts with different nucleophiles, e.g. amines and alcohols without contamination of reaction mixture since there is no leaving group but HCl.

TOS-BB-1316

TOSLab Building-Blocks database is updated and includes now new unique reagent, bearing three chiral centers: (2R,3S,5R)-5-azidotetrahydrofuran-2,3-diyl bis(4-chlorobenzoate).

Due to its active azido group it could be used for insertion the ribose-like moiety into different structures.
