Abstract
Reaction of 5-methyl-4,5,6,7-tetrahydrofuro[3,2-c]- (1) and 6-methyl-4,5,6,7-tetrahydrofuro[2,3-c]pyridine (2) with hydrochloric acid gave novel dimerized compounds 3a-d and 4a-d, respectively. The structures of 3a, 3b, 4a and 4b were determined by spectroscopic method, and 3c, 3d, 4c and 4d by single crystal X-ray analysis. The reaction courses for the formation of these compounds are proposed.
