Abstract

2‐C‐Methylene‐N‐glycosyl amides have been obtained from 2‐(hydroxymethyl)glycals through a facile aza‐Claisen rearrangement. This rearrangement has also been utilized in the synthesis of L‐allo‐deoxynojirimycin, a moderate inhibitor of human lysosomal α‐mannosidase (IC~50~ = 64 μM), and two new C‐5‐(hydroxymethyl) analogues of L‐altro‐deoxynojirimycin and L‐ido‐deoxynojirimycin.(© Wiley‐VCH Verlag GmbH & Co.

## Abstract A systematic synthetic strategy has been developed for producing uncommon piperidine 1,2‐dideoxy‐L‐azasugars. This method involves the formation of open intermediates such as **2**, **7**, and **10** easily by ring‐opening of D‐glycals with aqueous mercury(II) acetate/sodium borohydride

## Abstract A study of the regioselectivity of the Claisen rearrangement of __meta__‐allyloxy aryl ketones showed that the electron‐withdrawing carbonyl group has a major influence and strongly directs rearrangement to the more hindered __ortho__ position. However, when the ketone is part of a ring
