โœฆ Synopsis

The Diels-Alder reaction of methyl propiolate with 1-vinylcycloalkenes was used to assess the influence of ring strain on the regioselectivity of such cycloadditions:

the ratio of 1,2,3-to 1,2,4-adducts increased with increasing size of the cycloalkene.

In the course of work on the alkylation of heterocyclic ambident anions2j3 we have studied 3-hydroxyisoquinoline (1) and its alkylated derivatives. N-Methyl-3-isoquinolone (2) has been previously described as being unstable4 and as deteriorating rapidly. 5 We report on the oxidation and Diels-Alder
