## Abstract Some bridgehead nitrogen compounds possessing the CH(Me)‐bridgehead NC(O) system have been synthesised and their configurations assigned. The chemical shifts of the proton geminal to the methyl group provides evidence for the existence of a deformed chair conformation for the methyl su
## Abstract A series of perhydropyrido[1,2‐__c__][1,6,3]dioxazocines and 2‐alkylperhydropyrido[1,2‐__c__][1,3,6]oxdiazocines have been prepared. 6‐__p__‐Nitrophenyl‐3,4‐dimethylperhydropyrido[1,2‐__c__][1,6,3]‐dioxazodioxazocine is shown to adopt the __cis__ fused ring conformation in solution with
## Abstract A series of substituted hexahydropyrido [2,1‐__c__] [1,4] oxazin‐3(4__H__)‐ones has been synthesised, and the configurations of these bicyclic lactones assigned utilising chemical and spectral data. All the compounds adopt __trans__‐fused conformations and the conformation of the lacton
