experimental part, p. 915 - 926 (2010/05/01)
The oxa-Pictet-Spengler reaction with various aldehydes and-arylethanol yields 1-substituted-isochromans in the presence of bismuth triflate as catalyst in good yields. The method was extended to O,O-acetals to afford the corresponding 1,1-disubstituted-i
Zeolite-catalyzed simple synthesis of isochromans via the oxa-Pictet-Spengler reaction

, p. 1220 - 1222 (2007/10/03)
The synthesis of isochromans via oxa-Pictet-Spengler reaction using a modified small pore size zeolite E4 as catalyst was investigated. Ersorb-4 (E4) is a clinoptylolite-type zeolite material with high silicon content. The reaction of 2-phenylethanol deri
