3- Alkoxy-2- perhydropyrido oxazines

Alkoxy-3-(4-biphenyl)perhydropyrido[], 2-c][], 4]oxazines were obtained from 3-hydroxy derivative with PrOH and Br(CH2)30H in a boiling acidified medium (00JMC609, 00MIP13). Spontaneous dehydration of b-hydroxy-1,3,4,6,7,1 lZ -hexahydro[l,4]oxazino[3,4-n]isoquinolin-4-one 258 in CHCI3 gave 3,4,6,7-tetrahydro derivative 259 (97JOC2080).
