Esters, N,N-disubstituted amides, and a N-acylurea derived from the enantiopure industrial intermediate (1R)-cis-hemicaronaldehydic acid (or biocartol) are convenient synthons for the preparation of a series of chiroporphyrins by condensation with pyrrole

A new chiroporphyrin is prepared in 60% yield using complementary intramolecular hydrogen-bonding interactions between N-acylurea substituents to direct the cyclisation of the tetrapyrrolic intermediate; similar hydrogenbond assistance by carboxylic acid

Enantiopure esters are obtained in good yield from (1R,3S)-(-)-2,2-dimethyl-3-formylcyclopropane-1-carboxylic acid (biocartol) in three steps: (1) dithiane protection of the aldehyde function; (2) esterification of the carboxylic acid function; (3) dethio
