More Information
Summary:본 발명은 하기 일반식(Ⅱ)의 히드록시메틸테트라히드로피란(Ⅱ)을 동, 은 및(또는) 금 촉매 존재하에 탈수소화시킴을 특징으로 하는, 약제 또는 작물 보호제 합성의 귀중한 중간체인 하기 일반식(Ⅰ)의 포르밀테트라히드로피란(Ⅰ)의 제조 방법에 관한 것이다. Disclosed is a method for the preparation of formyltetrahydropyrans (I) by dehydrogenating hydroxymethyltetrahydropyrans (II) in the presence of a copper, silver and/or gold catalyst. The formyltetrahydropyrans (I) thus obtained are useful intermediates in the preparation of pharmaceuticals and phytopathalogical products.
