Novel bisheterocycles, 1,2,3βselenadiazoles, thiadiazoles and 2__H__βdiazaphospholes in combination with oxadiazoles, thiadiazoles and triazoles were prepared from phenacylsulfonylacetic acid methyl ester.

## Abstract magnified image Some bisheterocycles having pyrrole and oxazoline/thiazoline units were synthesized from __Z__βstyrylsulfonylacetic acid methyl esters using samarium chloride.
**Chemically synthesized Ξ±βamino acids** are used to fortify foodstuffs and animal feeds. The drawbacks of former syntheses are avoided in the reaction sequence __(1)__β__(2)__β__(3)__ which leads, __e.g.__ to lysine in an overall yield of 52% (X ο£Ύ Cl, Br; R^1^ ο£Ύ Me, Et; M ο£Ύ K, Na, Li) equation ima
