Abstract:The conjugate spontaneous addition of chiral N,N-dialkylhydrazines 1 to dimethyl alkylidene/arylidene malonates 2, 5–10 affords the corresponding β-hydrazino esters in moderate-to-good yields and selectivities. d-Mannitol-derived hydrazine 1a afforded best results, mainly due to the higher stability of the products 3, 11–16.
