Title:<\/strong>
Titanium isopropoxide-mediated\u00a0cis<\/em>-selective synthesis of 3,4-substituted butyrolactones from CO2<\/sub><\/a><\/p>\n\n\n\n

Abstract:<\/strong>
We report a Ti(OiPr)4<\/sub><\/small>-mediated multicomponent reaction, which produces 3,4-substituted\u00a0cis<\/em>-\u03b4-lactones from alkyl magnesium chloride, benzaldehyde and CO2<\/sub><\/small>. The key intermediate, titanacyclopropane, is formed\u00a0in situ<\/em>\u00a0from Ti(OiPr)4<\/sub><\/small>\u00a0and a Grignard reagent, which enables 1,2-dinucleophilic reactivity that is used to insert carbon dioxide and an aldehyde. An alternative reaction route is also described where a primary alkene is used to create the titanacyclopropane. A computational analysis of the elementary steps shows that the carbon dioxide and the aldehyde insertion proceeds through an inner-sphere mechanism. A variety of\u00a0cis<\/em>-butyrolactones can be synthesized with up to 7\u2006:\u20061 diastereoselectivity and 77% yield.<\/p>\n\n\n\n
