A new synthetic entry to (-)-lasubine I and (+)-subcosine I has been established by employing the (S)-allylalkoxy benzylamine as a chiral synthon. The synthesis involves the formation of an α,β-unsaturated lactone by RCM reaction followed by an intramolec
Dual activation in asymmetric allylsilane addition to chiral N-acylhydrazones: Method development, mechanistic studies, and elaboration of homoallylic amine adducts

Chiral N-acylhydrazones derived from commercially available 4-benzyl-2-oxazolidinone provide a rigid, conformationally restricted template to impart facial selectivity in additions to C=N bonds. In the presence of indium(III) trifluoromethanesulfonate [In

(Matrix presented) Trifluoroacetyl derivatives of hydrazines undergo clean and efficient reductive cleavage of the N-N bond with Sml2 in the presence of MeOH. After N-trifluoroacetylation, acyl-, aryl-, and alkyl-substituted hydrazines are redu
