“…The reaction was studied in detail, a reproducible microcondensation procedure developed, and the microesterification of tropine and tropic acid standardized (7). At the same time, a prototype procedure was developed for the microsynthesis of succindialdehyde and tropine from arabinose (9) which would be used to label the 1,5,6, and 7 positions of atropine.
