De, Surya Kanta
, p. 2339 - 2341 (2007/10/03)
Carbonyl compounds have been successfully converted into their corresponding oxathiolane, dithiolane, and dithiane derivatives with 2-mercaptoethanol, 1,2-ethanedithiol, and 1,3-propanedithiol using catalytic amount of yttrium triflate. In addition, by us
Synthesis of dibenzylbutyrolactone lignans: Total synthesis of arctigenin, pluviatolide and haplomyrfolin by tandem conjugate addition
Mitra, Jayati,Mitra, Alok Kumar
, p. 953 - 956 (2007/10/02)
The total synthesis of three dibenzylbutyrolactone lignans, arctigenin, pluviatolide and haplomyrfolin has been carried out by tandem cnjugate addition of dithiane carbanions to but-2-en-4-olide and substituted benzyl bromides leading to the formation of key intermediates which subsequently underwent debenzylation and desulphurisation.
