✦ Synopsis

Methyl a-isomaltoside and methyl a-isomaltotrioside specifically deoxygenated at position C-3 of various glucopyranosyl units were synthesized by condensation of either 1,6-di-O-acetyl-2,4-di-O-benzyl-3-deoxy-adg-D-ribo-hexopyranose (7) or 1,6-di-O-acetyl-2,3,4-tri-O-benzyl-a,~-D-glucopyranose [mediated by silver perchlorate and tin(IV) chloride] with suitably blocked derivatives of methyl a-D-glucopyranoside, its 3-deoxy analog (6), or methyl 3'-deoxy a-isomaltoside (10), respectively.

## Abstract A convenient synthesis of 5α‐[20β‐^2^H]pregnane‐3α,20α‐diol and 5α‐[20β‐^2^H]pregnane‐3β,20α‐diol from 3β‐hydroxy‐5α‐pregn‐16‐en‐20‐one is described. The reaction products are characterized by combined gas chromatography‐mass spectrometry.
