Abstract

Monolithiated 1,7‐dicarba‐closo‐dodecaborane(12) reacts with O‐isopropylidene derivatives of D‐erythrono‐1,4‐lactone (1), L‐mannono‐1,4‐lactone (3) and with tetra‐O‐trimethylsilylated D‐glucono‐1,5‐lactone (2) and D‐gulono‐1,4‐lactone (4) to give the title compounds after deprotection. An X‐ray structure analysis of the protected L‐mannofuranose carborane derivative 9 reveals that the more stable anomer has the β‐L configuration.
