Development of a new approach has permitted a fuller analysis of the stereochemistry of deazetation of the stereospecifically deuteriated azo compound (1d) than could be achieved previously, in that it has proved possible to analyse 2H2>octa-1,7-diene for E,E-, E,Z,-and Z,Z-content.This has given results for the thermal and photochemical reactions that can be rationalised in terms of partial conformational equilibration of the biradical.

Methods for the preparation of a series of model compounds which were required for stereochemical studies are described: the tricyclic O,N-ketenacetal 1, the two diastereomeric bicyclic amino acids 7 and 10 (see Scheme 2), and the two diastereomeric conformationally fixed tetrahydro-1,3-oxazines (=1,3-oxazines) 9 and 11.An x-ray analysis of racemic 1 reveals a quasi-tetrahedral nitrogen pyramid of the O,N-ketene acetal grouping, and an almost perfect conformational analogy between the N- and C-centered allylic positions at the double bond.
