[Figure not available: see fulltext.] A simple and convenient method for the synthesis of 2,5-disubstituted 1,3,4-oxadiazoles has been developed. Structurally divergent symmetrical and unsymmetrical 2,5-disubstituted 1,3,4-oxadiazoles can be obtained in moderate to high yields via NaOCl-mediated oxidative cyclization of N-acylhydrazones, generated in situ from aliphatic and aromatic hydrazides and aldehydes.

Reaction of N-acylhydrazones with benzyloxyacetyl chloride in the presence of i-Pr2EtN affords new 1,3,4-oxadiazolines in excellent yields (72-95%), under mild reaction conditions and in short reaction times. The structures of the products were confirmed by single-crystal X-ray diffractometry. A plausible reaction mechanism is proposed. Georg Thieme Verlag Stuttgart · New York.
Asymmetric Br?nsted acid catalyzed cycloadditions-efficient enantioselective synthesis of pyrazolidines, pyrazolines, and 1,3-diamines from N-acyl hyrazones and alkenes

A general, metal-free, highly enantioselective Bronsted acid catalyzed [3+2] cycloaddition between hydrazones and alkenes has been developed that affords pyrazolidine derivatives (see scheme). The resulting optically active pyrazolidines can undergo many chemical transformations which allow, for example, the enantioselective synthesis of valuable pyrazolines and 1,3-diamines. Copyright
