An Oppolzer's sultam-based highly stereoselective α-hydroxylation of amides was developed to deliver the desired products in good yield and excellent diastereoselectivity (>20/1). The generally crystalline products and the recyclability of the chiral auxiliary illustrate the practicability and scalability of the current approach.
Diastereoselective synthesis of the C14-C29 fragment of amphidinol 3

An efficient stereoselective synthesis of the C14-C29 fragment highlighting a coupling reaction between a 1,3-dithiane derivative and an α-branched aldehyde was realized. This highly convergent synthesis involved two chiral pools, l-malic acid and (+)-camphorsulfonic acid, which are the starting compounds to control the six stereogenic centers present in the C14-C29 fragment of amphidinol 3.
Synthesis of enantiomerically pure divinyl- and diallylcarbinols
Schmidt, Bernd,Wildemann, Holger
, p. 1050 - 1060 (2007/10/03)
Acylated oxazolidinones and bornane sultams can be cleaved to divinyl- and diallylcarbinols by treatment with vinyl- or allylmetal compounds. For the preparation of divinylcarbinols, acylated bornane sultams are the starting materials of choice, while for the preparation of diallylcarbinols acylated oxazolidinones and bornane sultams work equally well.
