, p. 3055 - 3063 (2007/10/02)
Complete details of a study leading to the asymmetric synthesis of the AB-ring system of (+)-sesbanimide A (1), a potent cytotoxic agent belonging to the class of sesbania alkaloids, are described.Key features of the synthesis include (a) the stereoselect

(R)-O-acetyl mandelic acid has been utilized for the development of a procedure for resolution and absolute stereochemical assignment of C1-oxygenated E-crotylsilanes 1a-c. The procedure is enhanced further by an efficient boron trifluoride etherate catal
π-facial selectivity in catalytic osmylation reactions of chiral C1-oxygenated allylic silanes
Panek, James S.,Cirillo, Pier F.
, p. 4873 - 4878 (2007/10/02)
Oxygen-substituted allylic and crotyl silanes undergo vicinal hydroxylations with unprecedented levels of diastereofacial selectivities in the presence of catalytic amounts of osmium tetroxide to predominantly form 1,2-anti-1,2,3-triol units. The magnitud
Allylic Transpositions of Enantiomerically Pure C1-Acyloxy (E)-Crotylsilanes: Stereospecific Synthesis of (E)-Vinylsilanes
Panek, James S.,Sparks, Michelle A.
, p. 5564 - 5566 (2007/10/02)
Treatment of (R)- and (S)-C1-acylated (E)-crotylsilanes 1 with catalytic amounts of boron trifluoride etherate or dichloropalladium bisacetonitrile in methylene chloride at room temperature resulted in allylic transposition of the ester gr
