Nereistoxin (I) was synthesized from 1, 3-bis(benzylthio)-2-propanol (III) via the intermediates (VI), (XIII), and (XV). The structures of some synthetic isomers were also discussed.
Compounds of the formula ##STR1## wherein R.sup.1 and R.sup.2 are independently benzyl substituted benzyl, phenyl or substituted phenyl, said substituted benzyl and substituted phenyl substituted on the phenyl ring with one or more substituents independently selected from the group consisting of halo, lower alkyl and trifluoromethyl; X and Y are independently oxygen or sulfur with the proviso that Y is not oxygen when R.sup.2 is phenyl or substituted phenyl; and the antimicrobial acid addition salts thereof are useful as antifungal, antibacterial and antiprotozoal agents.

The reactivity of tosylated glycerol carbonate 2 toward nucleophiles has been exploited to generate glycidol analogues protected with carbonate or carbamate groups. The activated glycerol 2 is a reasonable linking agent with thiol and alcohol nucleophiles and an excellent and selective one with primary amines, allowing efficient bis-functionalizations of glycerol.
