• Conjugate addition of amides to α,β-unsaturated esters by CsF-Si(OEt)4 system
  作者：Kyo Han Ahn、Seok Jong Lee

  DOI：10.1016/s0040-4039(00)73184-4

  日期：1994.3

  The conjugate addition of amides to α,β-unsaturated esters proceeds efficiently with an equimolar amount of Si(OEt)4 and a catalytic amount of CsF to afford the corresponding N-substituted amides.

  用等摩尔量的Si（OEt）4和催化量的CsF有效地将酰胺共轭加到α，β-不饱和酯上，得到相应的N-取代的酰胺。

  The present invention relates to the use of at least one caprolactam derivative of formula (I) below: in which: n=0 or 1; m=0 or 1; p=0 to 13; R 1 is a linear or branched alkyl radical comprising a number t of carbon atoms of from 1 to 20; subject to the following conditions: (i) when p=0, m=0, (ii) when p=1 and n=1, m=1, (iii) when p=1 and n=0, m=0 and R 1 denotes a C 2 -C 20 alkyl radical; with the proviso that the sum of p+t is between 3 and 20, in a composition comprising, in a cosmetically acceptable medium, at least one liquid fatty phase and at least one lipophilic active agent, and containing no dibenzoylmethane-type UV screening agent, as a solvent for said active agent in said liquid fatty phase and/or as an agent improving the solubility of said active agent in the solid fatty phase. The present invention also relates to a composition comprising, in a cosmetically acceptable medium, at least one liquid fatty phase, characterized in that it comprises at least one caprolactam derivative of formula (I) as defined above and in that it does not contain a dibenzoylmethane-type UV screening agent.

  A series of cylic diazoamides and diazoamines were synthesized. Treatment of these cylic diazoamides and diazoamines with a catalytic amount of rhodium(ll) acetate furnished the corresponding cyclic enamides and enamines,respectively. Interestingly, cyclic diazoamines produced stereoselectively Z-enamines.
