## Abstract The ‘naked sugar’ (+)‐(1__R__,2__R__4__R__)‐2‐__endo__‐cyano‐7‐oxabicyclo[2.2.1]hept‐5‐sn‐2‐__exo__‐yl acetate ((+)‐4) was converted (7 steps, 45% overall) with high stereoselectivity into (−)‐(4__R__,5__S__,6__R__)‐4,5,6‐tris{[(__tert__‐butyl)dimethylsilyl]oxy}cyclohex‐2‐en‐1‐one ((−)‐
Improved preparation of (±)-(1,3/2,4)-5-cyclohexene-1,2,3,4-tetrol [(±)-conduritol-B] and its reaction with hydrobromic and hydrochloric acid; synthesis and characterisation of some (±)-1-deoxy-1-halo- and (±)-1,4-dideoxy-1,4-dihaloconduritols

## Abstract The reaction of thiocarbohydrazide with carboxylic acids at the melting temperature allows an improved preparation of the S‐substituted 4‐amino‐3‐mercapto‐1,2,4‐triazole heterocycles. The crude 4‐amino‐5‐mercapto‐1,2,4‐triazoles react easily with carboxylic acids or carboxylic acid chlo
