Starting from our recently described synthon (+)-24, the enantiomerically pure 3,6:4,5:3',6':4,5'-tetraepoxy-4,5,4,5'-tetrahydro-&,~-carotene (34) and its 15,15'-didehydro analogue 32 were synthesized in eleven and nine steps, respectively (Scheme 4 ) . Chiroptical data show, in contrast to the pare

R,R)-Butanediol (dichloromethy1)boronate (1) with I equiv. allylmagnesium halide yields (R,R)-2,3butanediol (1 S)-(1 -chloro-3-butenyl)boronate (3) together with the diallylated product (R,R)-2,3-butanediol(1 -allyl-3-butenyl)boronate (4). The formation of 4 is unprecedented in reactions of a-chloro
## Abstract The ^13^C‐labelled putative erythromycin biosynthetic intermediates, ((2__S__,3__S__,4__S__,5__R__,6__R__,7__R__)‐3,6,7‐trihydroxy‐2,4,6‐trimethyl[1‐^13^C]nonan‐5‐olide and __S__‐2‐acetylaminoethyl (2__R__,3__S__,4__S__,5__R__,6__S__,7__R__)‐3,5,6,7‐tetrahydroxy‐2,4,6‐trimethyl[1‐^13^C]
A catalytic deuteration of protected 3,4-dehydro-L-proline using RuCI2(PPh3) 3 followed by RuO~-oxidation gave a 3,4-dideuterated L-pyroglutamic acid derivative which is considered to be a promising precursor for various deuterated amino acids. The present study demonstrates a stereoselective reduct
