Methods of synthesizing compounds of the Formula V: ##STR1## wherein X.sub.c is a chiral auxiliary, m is from 1 to 4, and R.sub.8 is hydrogen or --OH, are provided. Additionally, methods of synthesizing compounds of the Formula XII: ##STR2## wherein m is from 1-4; B is hydrogen or a blocking group; and R.sub.13 is a leaving group or a compound of formula R.sub.14 --N--R.sub.15 ; wherein R.sub.14 is hydrogen or branched or straight-chain C1-C6 alkyl; and R.sub.15 is hydrogen, C3-C8 cycloalkyl, or branched or straight-chain alkyl; are also provided. Novel compounds useful in the synthesis of cyclopentenes and carbocyclic nucleosides are further provided.
