摘要：
A cost-effective, operationally simple and eco-compatible protocol for the one-pot synthesis of photochromic pyrans by the reaction of propargyl alcohols as well as propargyl ethers with differently substituted phenols under ambient atmosphere in aqueous medium has been developed using beta-cyclo-dextrin hydrate as an efficient, recyclable and stable catalyst. This is the first report where beta-cyclodextrin hydrate acted as a catalyst for an organic transformation but beta-cyclodextrin alone failed.
