A one-pot preparation of the chiral reducing agent diisopinocampheylchloroborane (Ipc2BCl) from α-pinene and borane methyl sulfide has been developed. The procedure obviates isolation of the air and moisture sensitive reagent, making it useful

A one-pot preparation of the chiral reducing agent diisopinocampheylchloroborane (Ipc2BCl) from α-pinene and borane methyl sulfide has been developed. The procedure obviates isolation of the air and moisture sensitive reagent, making it useful for large scale operations. Asymmetric reduction of ketones using the in situ prepared Ipc2BCl is comparable to that using isolated reagent.
Conversion of a silylated hemiacetal into an α-bromoether using trimethylsilylbromide. Synthesis of platelet activating factor antagonist L-659,989

, p. 6953 - 6956 (2007/10/02)
An efficient synthesis of platelet activating factor antagonist L-659,989 has been achieved in ten steps from commercially available 5-iodovanillin. The key transformation converts a silylated hemi-acetal into an α-bromoether followed by a highly stereose
