Remote regio- and stereocontrol by the sulfinyl group: Diels–Alder reaction of sulfinyl dienols and 8,8-dimethylnaphthalene-1,4,5(8H)-trione

Add time:07/27/2019    Source:sciencedirect.com

Diels–Alder cycloaddition of 8,8-dimethylnaphthalene-1,4,5(8H)-trione with diastereomeric hydroxysulfinyldienes proceeded with high yields and good π-facial and regioselectivities. The hydroxysulfoxide moiety controls the regio- and stereoselectivities, through hydrogen bonds in the suggested transition state.
