  From the initial development of a homologous Morita–Baylis–Hillman reaction utilizing epoxides as electrophiles, the method was expanded to enable the exclusively organocatalyzed intramolecular allylation of enones and to develop the intramolecular MBH-type alkylation of activated alkenes. We successfully utilized both enones and unsaturated thioesters as the activated alkene component. This work,

  从利用环氧化物作为亲电子试剂的同源Morita-Baylis-Hillman反应的最初开发开始，该方法得到了扩展，可以使烯酮进行有机催化的分子内烯丙基化反应，并开发出分子内的活化烯烃MBH型烷基化反应。我们成功地利用了烯酮和不饱和硫酯作为活化的烯烃组分。使用化学计量的三烷基膦进行的这项工作以高收率得到了一系列功能化的五元和六元碳环。随着烯酮和硫酯的环烷基化，开发了允许使用亚化学计量量的膦催化剂的条件。结果，与使用化学计量的三烷基膦时获得的产率相比，可以有效地形成五元环和六元环，而收率几乎没有损失。我们首次分离出了MBH型中间体​​，该中间体表现出空前的geometry盐和酰基反式几何结构。

  The combined use of a catalytic amount of InX3 (X = OTf and NTf2) and 1-butanol was found to be effective in formal alkyne–aldehyde metathesis. With this catalytic system, aromatic alkynes reacted with aromatic aldehydes to give chalcones in moderate to good yields. Alkynals were efficiently converted into 5- to 7-membered cyclic compounds by intramolecular alkyne–aldehyde coupling.
