A rapid and high-yield synthesis of methylmalonyl coenzyme A is reported. The two-step procedure involves preparation of the thiophenyl ester of methylmalonic acid using dicyclohexylcarbodiimide as a condensing agent, followed by transesterification with coenzyme A, to yield methylmalonyl coenzyme A
5-Methoxytryptamine and L-tryptophan methyl ester were acylated with malonic acid, dimethyl malonate, or succinic anhydride to produce the corresponding N,N'-dicarbonyltryptamine derivatives. The analgesic activity was evaluated by the tail flick test. All of the compounds exhibited desirable analgesic potency. This

The carbon-carbon bond-forming reactions of 1-methyl-2-methylthiophenylpyridinium iodides with active methylene compounds (such as dimethyl malonate, malononitrile) using NaH as a base gave the 2-substituted methylene-1,2-dihydropyridine derivatives.

The cobalamin metabolism in chronic myelogenous leukemia (CML) was evaluated in 18 newly diagnosed and untreated patients by formiminoglutamic acid (FiGlu) and methyl malonic acid excretion (MMA) tests. A deoxyuridine (dU) suppression test of bone marrow cells was compared in

The volatiles emitted from cell cultures of myxobacterium Myxococcus xanthus were collected by use of a closed-loop stripping apparatus (CLSA) and analyzed by GC-MS. Two new natural products, (S)-9-methyldecan-3-ol ((S)-1) and 9-methyldecan-3-one (2), were identified and synthesized, together with other
