Indium-Catalyzed [2 + 2] Cycloaddition of Allylsilanes to Internal Alkynones.

PMID: 26584237
Org Lett. 2015 Dec 04;17(23):5843-5. doi: 10.1021/acs.orglett.5b03065. Epub 2015 Nov 19.

We have developed an indium-catalyzed [2 + 2] cycloaddition of allylsilanes to alkynones leading to selective cyclobutenone formation. The resulting cyclobutenones were readily converted to the oxidized products by Tamao-Fleming oxidation or the ring-opened products by an electrocyclic reaction.

BACKGROUND: Breast ultrasound findings regarding tumor margins are crucial in judging whether a tumor is malignant or benign. However, the relationships between the margins and clinicopathological characteristics remain largely unknown. In this study, we examined the clinicopathological characteristics of...
