Synthesis and biological evaluation of pyridinebetaine A and B

The synthesis of the marine natural products pyridinebetaine A and B is reported. The biological evaluation of pyridinebetaine A and B and several analogues as cytotoxic, antifungal and antiviral agents is also described. Unfortunately, none of the compounds tested showed relevant antifungal or cytotoxic activity. Only pyridinebetaine B reduced the Herpes simplex virus type 1 virus replication, though only weakly.

Organic sulfur mechanisms. 24. Preparation and reaction of 2-hydroxyethanesulfonyl chloride, the first hydroxyalkanesulfonyl chloride

2-Hydroxyethanesulfonyl chloride (1a) is readily made by reaction of an aqeous solution of 2-mercaptoethanol (4a) with chlorine.This is the first clearly proved preparation of a compound which is both an alcohol and a sulfonyl chloride.Reactions of 1a with water and alcohols evidently proceed largely by intramolecular cyclization to the transient β-sultone (2a), which then undergoes nucleophilic ring opening to form the products.In the presence of tertiary amines a minor but significant part of the reaction is shown by deuterium labelling to proceed via hydroxymethylsulfene (14), the principal reaction of which is simply to add the alcohol or water; only a small part, if any, of the sulfene (14) loses the hydroxyl group to give the ethenesulfonate derivatives (13 or 22).Aqueous chlorination of 3-mercapto-1-propanol gave 3-chloro-1-propanesulfonyl chloride (5a) and 1,3-propane sultone (2b) with no sign of any 3-hydroxy-1-propanesulfonyl chloride (1b).A mechanism for the aqueous chlorination process invoking a cyclic chlorooxasulfoxonium ion (27) is discussed.
