Vs. Rao, A CONVENIENT PREPARATION OF 1-MERCAPTO-3-AZIDOCYCLOBUTANE FROM 1,1-CYCLOBUTANEDICARBOXYLIC ACID, Synthetic communications, 23(20), 1993, pp. 2915-2920
A convenient method for the preparation of cis- and trans-1-mercapto-3
-azidocyclobutane from 1,1-cyclobutanedicarboxylic acid is described.
The long range ''W'' coupling pathway was used to distinguish the cis
isomer from the trans isomer.
