Enol ether reaction with azetidinone

As discussed in Section 2.3.3.1, enol stannyl ethers react with carbonyl compounds readily without the need for catalysts. However, catalytic amounts of AgBp4 and h have bron found to improve considerably the yield of the condensation of the tin(II) enol ether (159) with the azetidinone (93). The use of a catalytic amount of PdCl2[P(o-MeC6H4)3]2 improves the yield of the reactions between enol stannyl(IV) ethers and aldehydes. ... [Pg.624]

Of the new methods of preparation of oxo derivatives of the 5,6-dihydro-4//-1,3-oxazines, the most important is that developed by Martin and co-workers 169 the reaction of acylisocyanates with enol ethers at room temperature under nitrogen yields 48 [Eq. (35)] (see also Arbuzov et a/.170-171) together with an isomeric azetidinone. The... [Pg.22]
