A reaction of cyclohexanone phenylhydrazone with (het)aryldihalogenophosphines has been studied. As shown, cyclohexanone phenylhydrazone reacts with phenyldibromophosphine and 5-methyl-2-furyldibromophosphine to provide the corresponding 1,2,3-diazaphospholines in high yields. The diazaphospholines thus obtained have been derivatized. © 2005 Wiley Periodicals, Inc. Heteroatom Chem 16:81–83, 2005; Published online in Wiley InterScience (www.interscience.wiley.com).

An environmentally benign approach for the synthesis of acridines using inorganic solid supports and “neat reaction'' technology is described. These methodologies completely eliminate the use of solvent during the course of reaction. Moreover, microwave‐assisted reactions reduce the reaction time from hours to minutes with improved yield. © 2005 Wiley Periodicals, Inc.

Disulfides of 1,4‐naphthoquinone were synthesized, and different methods of their synthesis were investigated. High yields and purity of disulfides were obtained from the oxidation of thiol derivatives. The latter were prepared in high yields and purity from isothiuronic salts. The obtained disulfides are syntho‐ nes for compounds with a wide spectrum of biological activity. © 2005 Wiley Periodicals, Inc.

Sulfenylchlorides, sulfenates, and sulfenamides of 1,4‐naphthoquinone were synthesized, and different methods of their syntheses were investigated. Synthesized sulfenates and sulfenamides are stable due to the large electron‐withdrawing potential of the conjugated quinonic system. Obtained mono‐ and bi‐functional sulfenderivatives are very important in organic synthesis of different new heterocyclic compounds. © 2005 Wiley Periodicals, Inc.

Optically active 1‐substituted taurines, a type of important sulfur analogues of naturally occurring amino acids, and their N‐benzyloxycarbonyl‐protected derivatives were synthesized from the corresponding optically active β‐amino secondary alcohols in three steps via N‐protection with benzyl chloroformate, substitution with thiolacetic acid under Mitsunobu conditions, and oxidation with performic acid. © 2005 Wiley Periodicals, Inc.
