Региоселективное взаимодействие 2-фенил-1-этинилдиэтилалюминия с 2,2-диметил-1,3-диоксоланом

Abstract

2-Фенил-1-этинилдиэтилалюминий, взятый в двойном избытке, селективно реагирует с 2,2-диметил-1,3-диоксоланом в мягких условиях (20 оС, 4 ч, растворитель гексан), образуя единственный продукт 2-[(1,1-Диметил-3-фенил-2-пропинил)-окси]-1-этанол с выходом 63%, расщепление диоксоланового цикла проходит по связи С1-О2 с участием исключительно алкинильной группы алюминийорганического реагента и не сопровождается какими-либо трансформациями тройной связи.

2-Phenyl-1-ethynyldiethylaluminium, taken in double surplus, selectively reacts with 2,2-dimethyl-1,3-dioxolane in soft conditions (20 оС, 4 h, hexane), forming a one product 2-[(1,1-dimethyl-3-phenyl-2-propinyl)-oxy]-1-ethanol with an yield of 63%. Splitting of dioxolane cycle takes place on connection С1-О2 with participation exclusively alkynyl group organoaluminium reagent and is not accompanied by any transformations of threefold connection.
