The indolizine ring is isomeric and isostructural to indole, and substituted indolizines are frequently prepared as bioisosters of biologically active indole derivatives. A well-known class of psychotropic indole compounds (e.g., psillocine, psylocibine and pindolole) belongs to the family of 5-hydroxy(alkoxy)indoles. An isostructural class of indolizines bearing 5-OR group (A in Scheme 1) may serve
