A mild, chemoselective and sustainable biocatalysed synthesis of sulfoxides has been developed exploiting CALB and using AcOEt with a dual role of more environmentally friendly reaction solvent and enzyme substrate. A series of sulfoxides, including the drug omeprazole, have been synthesised in high yields and with excellent E-factors.
Synthesis of substituted tetrahydrofurans via intermolecular reactions of γ-chlorocarbanions of 3-substituted 3-chloro-propylphenyl sulfones with aldehydes

Carbanions of 3-substituted-3-chloropropyl phenyl sulfones add to carbonyl groups of aldehydes to produce aldol type adducts that undergo 1,5-intramolecular substitution giving 2,3,5-trisubstituted tetrahydrofurans. The effect of substituents in the 3-pos
One-step Synthesis of Functionalized Dioxaspirodecanes from β-Phenylsulfonyl Dihydrofurans and γ-Lactones
Carretero, Juan C.,Diaz, Nuria,Rojo, Javier
, p. 6917 - 6920 (2007/10/02)
A one-step synthesis of differently substituted 1,6-dioxaspirodecanes from readily available starting materials is described.The process is based on the condensation of the α-anion derived from β-phenylsulfonyl dihydrofurans with γ-lactones.The spirocyclization occurs with high stereoselectivity at C-4, C-5 and C-9, but not at C-2.
