facile and direct highlystereoselectivesynthesis of [E]- and [Z]-allyl dithiocarbamates has been accomplished fromacetates of Baylis–Hillman (BH) adducts in catalyst-free one-pot three-component coupling reactions of carbon disulfide and amine in water under a mild and green procedure with high yields. The reaction pathway involves the nucleophilic displacement (SN2′) of BH acetates by dithiocarbamate
