โœฆ Synopsis


Oxaspiro[2.2]pentanes have recently been reported; 394 the synthesis and reactivity of this new heterocyclic system promises to be of considerable synthetic and mechanistic interest. We have found per-acid oxidation of methylenecyclopropanes provides a convenient synthesis of several l-oxaspiro[2.2]pentanes. We report here on the forumtion of some oxaspiropentanes, their thermal reactivity, and their conversion to cyclobutanones with Lewis acids.

As part of a study on additions to strained olefins and synthesis of strained nitrogen heterocycles, we have found that addition of methoxycsrbonylnitrene to 1,2dimethylcyclobutene, 2, and l-methylcyclobutene, 2, provides a convenient synthesis of the corresponding 5-azabicyclo[2.l.O]pentanes 2a and
