An efficient, one-pot synthesis of trithiocarbonates from the corresponding thiols using the Mitsunobu reagent

A novel Mitsunobu-based protocol has been developed for the synthesis of a variety of symmetrical and unsymmetrical trithiocarbonates from primary, secondary and tertiary thiols using carbon disulfide, in good to excellent yields. This protocol is mild and efficient compared to other reported methods.

A HIGH YIELDING, ONE-POT SYNTHESIS OF S,S-DIALKYL DITHIOCARBONATES THROUGH THE CORRESPONDING THIOLS USING MITSUNOBU’S REAGENT

A novel Mitsunobu-based technique has been developed for the synthesis of a variety of symmetrical and unsymmetrical S,S-dialkyl dithiocarbonates from various corresponding primary, secondary and tertiary thiols using gaseous carbon dioxide, in good to excellent yields.

BASIC RESIN MEDIATED EFFICIENT ONE-POT SYNTHESIS OF CARBAZATES FROM THE CORRESPONDING ALKYL HALIDES

A quick and efficient, one-pot synthesis of carbazates was accomplished in high yields by the reaction of various primary, secondary, and tertiary alkyl halides with a variety of substituted hydrazines using Amberlite IRA 400 basic resin/CO2 system. The reaction conditions were mild with simpler work-up procedures than the previously reported methods.

Triton-B-Catalyzed, Efficient, One-Pot Synthesis of Carbazates Through Alcoholic Tosylates

Abstract A quick, efficient, one-pot synthesis of carbazates was accomplished in high yields by the reaction of various tosylates of primary, secondary, and tert alcohols, with a variety of substituted hydrazines using the benzyltrimethylammonium hydroxide (Triton-B)/CO2 system. The reaction conditions are mild with simpler workup procedures than the reported methods.

An Efficient One-Pot Synthesis of Carbazates and Dithiocarbazates through the Corresponding Alcohols Using Mitsunobu's Reagent

A novel Mitsunobu-based protocol has been developed for the synthesis of carbazates and dithiocarbazates through the variety of corresponding primary, secondary and tertiary alcohols and various kinds of substituted hydrazines using Mitsunobu’s reagent and CO2/CS2 system, in good to excellent yields.

Triton-B-Catalyzed, Efficient, Solvent-Free Synthesis of Benzopyrans

A convenient and microwave-promoted novel protocol for the syntheses of diverse kinds of substituted benzopyrans from the corresponding variety of substituted hydroxy acetophenones and keto compounds using benzyltrimethylammonium hydroxide (Triton-B) under solvent-free conditions has been developed. This protocol is mild and efficient than the other reported methods.
