Abstract
A green approach to the synthesis of arylidene-substituted spiro[4,5]decan-8-one derivatives was successfully realized via the mild, base-catalyzed reaction of aromatic aldehydes with 1,4-dioxa-spiro[4.5]decan-8-one in water under microwave irradiation. This protocol has the prominent advantages of environmental friendliness, short reaction time, excellent yields, low cost, easy operation, and broad scope of applicability.
