Catalytic hydrophosphorylation of alkyl- and acylhydrazones
N-Boc- and N-acylhydrazino phosphonates were obtained for the first time by hydrophos- phorylation of the appropriate hydrazones of aliphatic and aromatic aldehydes and heterocyclic and aliphatic ketones in the presence of [tetra(tert-butyl)phthalocyanine
A short access to 3-hydroxy-4-hydroxymethyltetrahydrofurans: Application to the total synthesis of amphiasterin B4
The first total synthesis of amphiasterin B4, a secondary metabolite previously isolated from Plakortis quasiamphiaster has been achieved. The core structure has been reached according to a highly stereoselective one-pot epoxidation/cyclization of an unsa

A novel, one-pot synthesis of α-C-cyanohydrazines in the presence of lithium perchlorate/diethylether solution (5.0 M)
Condensation of N,N-dimethylhydrazine, an aldehyde in lithium perchlorate/diethylether solution (5.0 M) gave N,N-dimethylhydrazone, which were treated with trimethylsilylcyanide to afford α-C-cyanohydrazine. These compounds are important precursors of nitrogen-substituted reagents.
