Synthesis and molecular structure of 9-(arylidene)amino-11-(2-hydroxyphenyl)-8-oxa-12-azatricyclo[7.3.1.02,7]trideca- 2(7),3,5-trienes formed by cascade reaction of 2,6-di(2-hydroxy-phenyl)- 4-oxopiperidines with arylaldehydes and ammonia

Six novel 9-(arylidene)amino-11-(2-hydroxyphenyl)-8-oxa-12-azatricyclo[7.3.1.02,7]-tridecatrienes incorporating formally 1,5-oxazocine moiety were synthesized by one step protocol from 2,6-di(2-hydroxyphenyl)-4-oxopiperidines with aromatic aldehydes and ammonium acetate. © ISUCT Publishing.
