Msi. Makki et al., SYNTHESIS OF IHYDRO-OXAZOLO[3,21,2]PYRROLO[3,43,2]PYRIDIN-5-ONE AND HYDRO-OXAZOLO[3,21,2]-PYRROLO[3,42,3]PYRIDIN-5-ONE, Journal of the Indian Chemical Society, 71(2), 1994, pp. 75-79
A variety of 2-aryl-2,3-dihydro-oxazolo[3,2 : 1,2]pyrrolo[3,4 : 3,2]py
ridin-5?? -one and 2-aryl-2,3-dihydro-oxazolo[3,2 : 1,2]pyrrolo[3,4 :
2,3?? ]pyrrolo[3,4 : 2,3]pyridin-5-one were prepared. The absolute con
figuration of the chiral centers were studied thoroughly from which th
e structural and stereoformulae of these compounds were deduced by usi
ng nmr and micro-analysis technique.
