The acceptors were synthesized following the procedures shown in Scheme 2. 2 was converted into the corresponding sulfonyl amide 3 by first converting it into the sulfonyl chloride, followed by quenching with ammonium hydroxide. Next, both enantiomers of 3 were reacted with troc-chloride. Interestingly, if the reaction is left for 20 hours, a ditrocylation occurs yielding compound 4-(S) as the major product, whereas, if the reaction time is reduced to 30 minutes compound 5-(R) is obtained through monotrocylation. However, following a procedure from Huang et al. it was possible to selectively remove only one of the troc-groups from 4-(S) to obtain 5-(S).
