The Lewis-acid-promoted addition of prochiral E- and Z-allyl nucleophiles to chiral α-alkoxy N-tosyl imines is described. Alkene geometry is selectively transferred to the newly formed carbon-carbon bond, resulting in stereochemical control of C1, C2, and C3 of the resulting 2-alkoxy-3-N-tosyl-4-alkyl-5-hexene products. A computational analysis to elucidate the high selectivity is also presented. This methodology was employed in the synthesis of two naturally occurring isomers of clausenamide.
A Concise Synthesis of the Key Tetrahydrofuran Moieties of Caruifolin A and EBC-342

A common strategy for the concise synthesis of the key tetrahydrofuran moieties of caruifolin A and EBC-342 is presented. Asymmetric dihydroxylation and intramolecular SN2-cyclization are key strategic reactions for the synthesis of the furan f
Synergistic substrate and catalyst effects in the addition of trimethylsilyl cyanide to imines derived from lactic acid
Fields, Alexander M.,Jones, Simon

Trimethylsilylcyanide was added to various imines derived from (2S)-ethyl lactate in the presence of Lewis acids to provide both syn- and anti- β-hydroxy-α-aminonitrile stereoisomers. Syn-products were found to be the major in most instances, however, ant
