Spiroheterocycles were used as nitric oxide synthesis inhibitors." Photochromism of indolinospirochromens containing condensed 19 fragments in the indoline part of the molecule were achieved. As continuation to our interest in this area" encouraged us to suggest the synthesis of some new spiroheterocycles of pyrans containing indoline moiety. Experimental The time required for completion of each reaction was monitored
