  Morita–Baylis–Hillman adducts as building blocks of heterocycles: a simple approach to 4-substituted pyrazolones, and mechanism investigation via ESI–MS(/MS)

  摘要：

  We describe herein an efficient approach for the preparation of 4-substituted 2,3-dihydro-1H-pyrazol-3-ones starting from Morita-Baylis-Hillman adducts. These heterocycles were obtained in two or three steps as single isomers with moderate to good overall yields. One efficient and alternative methodology for the synthesis of alpha-methyl-beta-ketoesters is also reported (up to 91 % yield). Additionally, the mechanism of formation of pyrazolones was investigated employing ESI-MS/MS reaction monitoring.

  An efficient, environmentally benign, eco-friendly protocol for selective oxidation of primary and secondary Baylis–Hillman alcohols to the corresponding carbonyl compounds has been developed. We have demonstrated the catalytic use of o-iodoxybenzoic acid (IBX) generated in situ from 2-iodosobenzoic acid (IBA) in the presence of oxone (2KHSO5·KHSO4·K2SO4) as a co-oxidant. This efficient method notably
