At -78 C, with very slow addition of sulfuryl chloride, cyclic sulfates were formed in good yields, proved to be very reactive with nucleophiles and rapidly decomposed on attempted storage. Reaction of a cyclic sulfate with sodium azide yielded a trans -azidohydrin without evidence of allylic rearrangement occurring.

    Asian Journal of Chemistry Vol. 19, No. 7 (2007), 5747-5750 Synthetic Utility of Dimethyl Formaminium Chloride Chlorosulphate in Preparation of Cephems DAROGA SINGH*, BISHWA PRAKASH RAI and VANDANA SINGH Department of Chemistry, T.D. Postgraduate College, Jaunpur-222 002, India E-mail: [email protected] Dimethyl formaminium chloride chlorosulphate, a stable complex formed from sulphuryl chloride/dimethyl formamide and its synthetic utility in the preparation of different cephem antibiotics described. Key Words: Cephem, Silylation, Activation, Dimethyl formaminium chloride chlorosulphate. INTRODUCTION Synthesis of various cephalosporin antibiotics (I) mainly involves the acylation of 7-amino cephalosporanic acid (7-ACA) or 7-ADCA deriva- tives with corresponding carboxylic acid derivatives. Different methods for acylation reaction are reported in literature1-4. The activation of carboxylic acid is generally carried out by making acid chloride5, which is then condensed with the corresponding 7-amino nucleus. Another method involves the condensation of silylated cephalosporin nucleus with corre- sponding acyloxy phosphonium chloride derivative which is prepared from triphenyl phosphine (TPP), hexachloro ethane or CCl4 with corresponding 6,7 carboxylic acid . In the preparation of cefotaxime and ceftriaxone, SOCl2/ DMF complex is used to activate organic acid which is in situ condensed 8 with 7-amino moiety . The stability of this complex formed from SOCl2/ DMF is poor specially in solvent like toluene or benzene is the limitation of this process. Dimethyl formaminium chloride chloro sulphate (DFCCS) (II) in stable 9-11 complex formed by the reaction of SO2Cl2 with DMF . It has been used as chlorinating reagent for aromatic and heterocyclic nucleus12,13. The present article describes the utility of DFCCS for preparation of various cephalosporin antibiotics.

  • Natural Kaolinitic Clay: a Remarkable Catalyst for Highly Regioselective
    Indian Journal of Chemistry Vol. 45B, April 2006, pp. 972-975 Natural kaolinitic clay: A remarkable catalyst for highly regioselective chlorination of arenes with Cl2 or SO2Cl2 B Jayachandran, Prodeep Phukan,# Thomas Daniel & A Sudalai* National Chemical Laboratory, Pune 411 008, India E-mail: [email protected] Received 30 September 2004; accepted (revised) 7 November 2005 Natural kaolinitic clay containing transition metals s as Fe and Ti in its lattice has been found to exhibit unusual regioselectivity in the liquid-phase chlorination of arenes with either Cl2 or SO2Cl2 as the chlorinating agent para-Chlorinated products are predominant for most of the substrates with an exceptional case of ortho-selectivity for the chlorination of aniline. Keywords: Chlorination, chlorine, sulfuryl chloride, aniline, ortho-chloroaniline IPC: Int.Cl.7 C 07 C Introduction of chlorine into aromatic rings by acids such as zeolites for the chlorination of arene4. electrophilic substitution is an important synthetic Although para-selectivity was achieved using zeolite4 transformation because chlorinated hydrocarbons are because of it’s shape selective nature, there is not such recognized as versatile starting materials and additives report for ortho-selective chlorination. Sheldon in th e p rod uctio n o f h igh qu ality in secticides, reported a highly regioselective ortho-chlorination of 1 fungicides, herbicides, dyes, pharmaceuticals etc. phenol with SO2Cl2-amine systems in homogeneous Moreover, they can serve as precursors for numerous phase5. In recent years, acid catalysis of organic functionalities, such as phenols, aromatic ethers and transformations by clay aluminosilicates6 is an area of thioethers, amines, aryl hydrazines, benzonitriles, considerable potential and interest due to the ease of benzaldehyd es, fluoro aromatics and arom atic handling and w ork-up, absence o f toxicity and hydrocarbons2.
