Study of the Michael addition of β-cyclodextrin–thiol complexes to conjugated alkenes in water

An environmentally benign and highly efficient supramolecular Michael addition of thiols from the secondary side of beta-cyclodextrin to alpha,beta-unsaturated compounds at the primary side in water is described in quantitative yields; products of undesirable side reactions resulting from polymerization are not observed; the use of cyclodextrin precludes the use of either acid or base and the catalyst can be recovered and reused.

Conversion of Epoxides to β-Chlorohydrins with Thionyl Chloride and β-Cyclodextrin in Water.

Abstract Several epoxides are efficiently converted to the corresponding β‐chlorohydrins in impressive yields with thionyl chloride in the presence of β‐cyclodextrin using water as solvent at room temperature.

ZnCl2 : Simple and efficient catalyst for the allylation of aldehydes with allyltributylstannane

Abstract A simple and efficient procedure for the allylation of aldehydes with allyltributylstannane promoted by zinc chloride under mild conditions to give the corresponding homoallylic alcohols is reported in excellent yields. IICT Communication No. 050702.

Efficient regioselective ring opening of oxiranes with thioacids in the presence of β-cyclodextrin in water

Abstract A mild and convenient synthesis of β‐hydroxy thioesters has been achieved by the regioselective ring opening of oxiranes using thioacetic acid and thiobenzoic acid in the presence of β‐cyclodextrin in water at room temperature. β‐Hydroxy thioesters are realized in high yields, and β‐cyclodextrin can also be recovered and reused.

Deprotection of Oximes using Iodosobenzene in the Presence of β‐Cyclodextrin in Water

Abstract A mild and efficient method for the regeneration of carbonyl compounds from oximes at room temperature in impressive yields has been developed using iodosobenzene/KBr in the presence of β‐cyclodextrin in water. IICT Communication No. 051010.
